1. Interviewing.io Features
Before we go through the pros and cons of signing up for Interviewing.io, let’s first take a look at their website’s features and services.
1.1 Mock interviews
With experts
Interviewing.io provides anonymous mock interviews with tech experts. Topics you can cover include coding, system design, machine learning, and many more. You can also request to get matched with an expert from your target company. The sessions are anonymous, so they will be voice- and text-based only.
With peers
When you sign up for Interviewing.io, you get 1 free peer mock interview session. You can unlock more sessions by conducting peer mock interviews yourself.
With an AI interviewer
To access the free AI interviewer, you’ll need to sign up for a membership. This feature claims to mimic a FAANG mock interview and lets you practice the questions from the website’s own Beyond Cracking the Coding Interview.
1.2 Free resources
Interview replays
Interviewing.io has a library of mock interview videos from actual sessions, posted with the permission of both participants. Each replay includes a video of the session, a written solution, and a transcript of the entire interview. It also has detailed feedback from the interviewer and interviewee.
Interview guides
The website has a few written interview guides on company-specific interview processes, interview questions per coding language, and sample answers to popular questions.
1.3 Hiring channel
Aside from offering mock interviews to engineers, Interviewing.io is also a hiring channel for employers. Through the website’s tech interview performance data, they introduce high-performing candidates directly to employers.
2. Interviewing.io Review: Pros and Cons↑
The first thing to say is that Interviewing.io is completely legitimate and credible, and from our research in forums such as Reddit and Blind, the majority of customer experiences seem to be positive.
But that doesn't necessarily mean it's the right option for you, or value for money for your specific situation.
Let's run through a few pros and cons about the service.
1.1 Interviewing.io pros
Coaches
Interviewing.io only accepts coaches who've run at least 20 interviews at FAANG/similar companies, and it asks them to do 2 trial interviews to ensure they reach the required standards.
Anonymity
What makes it different from other mock interview websites is that it’s completely anonymous. Many find this feature comfortable, especially candidates who worry about their colleagues finding out they’re in an interview process.
ROI
Doing mock interviews with an expert from your target company helps you improve your interview performance in a way that just knocking out problems on Leetcode can not. And if you're going for a job at the likes of Google, Meta, or Amazon, spending a few hundred dollars on mock interviews is small change when put against the salary gains you stand to make.
Expertly written guides
Interviewing.io doesn't have a lot of content on its blog, but the resources it does have are first-class. Its system design interview guide, for example, is a simply outstanding resource. Its detailed interview replays are also a great resource for anyone who wants to see how a mock interview at the website is run.
Reduced hiring bias
If you’re an employer, hiring via Interviewing.io helps you reduce inherent bias, since you’re hiring based on actual tech interview performance. For engineer candidates who have faced biased hiring hurdles, this is also a great benefit.
Overall, Interviewing.io is a solid option for experienced engineers looking to improve their interviewing skills and get scouted. But some drawbacks mean it’s not right for everyone. Let's take a look.
1.2 Interviewing.io cons
Pricing
Mock interviews start at $225, making it significantly more expensive than many of its competitors. The price can increase depending on the subject matter and whether you want an interviewer from a specific company.
Sign-up hurdles
When you sign up, there’s no guarantee you’ll be able to get its services right away. You could be put on a waitlist, or your region might not be supported yet. At the time of writing, Interviewing.io supports North America and some countries in Latin America.
No option to choose a mentor
Interviewing.io doesn’t list its coaches, nor does it let you choose your own. You can request a coach from a specific company, and Interviewing.io will take care of the match.
Not for beginners
If you’ve yet to experience technical interviews, we don’t recommend Interviewing.io for you. It’s best for users who have some technical interview experience and are already familiar with the format.

3. Interviewing.io Pricing↑
Unlike some other sites that clearly show the pricing upfront, Interviewing.io isn't super clear about the cost of doing mock interviews. Prices start at $225 per mock interview, but that could go up depending on the coach you get matched with.
Presumably, the more experienced the coach (and the more prestigious their resume), the more you pay. You also pay more if you request a specific company.
$225 is on the expensive side, when you consider that on a site like IGotAnOffer, you can book coaches who've worked at Meta or Google for 10+ years for 2, 3, 4, or 5 credits (1 credit=$50) per coaching hour.
However, Interviewing.io does give you some nice bonus features, like 1 free peer mock interview upon sign-up, and recording and storing your interviews so you can watch them back at your leisure.
4. Interviewing.io Alternatives (Top 3)↑
With these Interviewing.io limitations in mind, we’ve drawn up a shortlist of what we think are the three best tech interviewing coaching services available right now for candidates who want to improve their interviewing skills.
#IGotAnOffer
IGotAnOffer is a coaching platform where you can book mock interview sessions. It also offers career mentoring, leadership coaching, resume review, and salary negotiation coaching sessions.
There are over 300 coaches on the platform, and they’ve all worked at the very top companies in tech (e.g., Google, Meta, Amazon, etc.). You can filter your coach options based on company, mock interview specialty, target role and industry, location and availability, and coach badges. You can clearly see a coach’s profile, something you can’t do on Interviewing.io.
Most of the coaches specialize in product management or engineering interviews, so they will be well-equipped with real-world insights to guide you through the interview process in your chosen role and target company.
Prices are clearly displayed before you book, and if you’re not satisfied with your session, you get a full refund.
#TryExponent
TryExponent is one of the leading platforms for tech candidates looking to land their dream job. The site is packed full of resources, and while it’s mainly known for its courses, it also does interview coaching. You’ll find a good range of software engineer or PM coaches with experience at top FAANG companies.
However, the price is a bit high, almost comparable to Interviewing.io sessions. In fact, if you go to IGotAnOffer instead, you can often book a session with the exact same coach for $60 less!
If you’re committed to improving your interviewing skills and have the budget for it, get the Ace the Interview Program. It includes a readiness assessment, 5 mock sessions, 1-year access to courses, and 20% off for other coaching services at $1499. You can also join its scheduled mocks with other candidates in their Peer Mocks section for free practice.
Check out our article on Exponent to learn more about its services and alternatives.
#Tech Mock Interview
Tech Mock Interview offers mock interviews for tech candidates, among other job application services. Browsing their mock interviews page, you’ll find that interview coaches offer different rates based on their years of experience, expertise, and session duration, so there’s a price range for every budget.
The Tech Mock Interview coach page itself is very straightforward. You can immediately filter your coach options based on the coaching service you need. You can also filter based on the subject matter expertise for which you need coaching: coding, system design, software development manager, technical program manager, behavioral, machine learning, and data science.
However, its selection of coaches is small. You will find a wider selection of experts who can coach you on the same subjects on IGotAnOffer.
5. More Interviewing.io Alternatives (Categorized)↑
5.1 If you’re looking for budget-friendly options
#Pramp
Pramp is a website where you can schedule mock interviews with peers. It's been recently acquired by Exponent, so you need to link your former Pramp account to Exponent to use the service. If you have a free account, you get 5 credits per month. If you want more, you'll need to subscribe to Exponent.
Its interface and customer service get good reviews from users, though the actual mocks vary from great to not-so-great. It’s a good place to start your interview prep before investing in a mock with an expert on a platform like IGotAnOffer.
Just like Interviewing.io, you can’t choose who you’ll have your peer mock session with. Based on the information you give at sign-up, Pramp will match you with the best peer. You can, however, use the “invite session” feature if you want to use its platform to practice with a friend.
Check out our article on Pramp to learn more about its services and alternatives.
#Tech Mock Interview
Tech Mock Interview has a good roster of expert tech coaches. Each coach offers different rates based on their years of experience, expertise, and session duration, so there’s a price range for every budget. Click on a coach’s profile and you’ll instantly see a calendar for their available schedules.
5.2 If you’re looking for a wider range of coaches↑
#IGotAnOffer
If you want to choose your mock interview coach, IGotAnOffer is an excellent option. It has hundreds of coaches from top companies, including Meta, Amazon, Apple, Netflix, Google, and many more. They represent many roles, from software engineers to data scientists to product managers. You can also filter based on mock interview type.
Compared to Interviewing.io, IGotAnOffer doesn’t charge a premium for you to get a coach from your target company. You simply filter your options based on company, and you can see various coaches with their different price ranges.
You also have the flexibility of choosing how you want to use your credits. You can spend them all with one coach, or divide them between coaches to get different perspectives.
#Prepfully
Prepfully is similar to Interviewing.io in that it offers anonymous mock interview sessions with experts. What makes it better is that it gives you the option to choose your own coach, or have the website itself do the match for you.
When you choose your own coach, you can pick one based on your budget. So if you can afford it, you can go with a more experienced coach (from $199 up). Or, if you’re on a tight budget, go with a coach with less experience or no completed sessions for $89 up.
One drawback to Prepfully is that it’s hard to filter your coach options. You only have two filter options: by role or by company. Meanwhile, at IGotAnOffer, you have several ways to filter your coaches, allowing you to find the best match more quickly.
5.3. Best Interviewing.io alternatives if you’re looking for next-day mock sessions↑
#IGotAnOffer
If you need a mock interview session ASAP, IGotAnOffer is an excellent option for you. Booking a session with one of its coaches from FAANG and other top tech companies is so easy and quick.
Unlike Interviewing.io, you won’t be put on a waitlist when you sign up. As soon as you sign up, you can instantly browse the coach options and then filter them based on the role or company you want to apply to. You can see the coaches' hourly availability and book your online session in a couple of clicks, something you often can’t do on Interviewing.io. And if you’re not satisfied, you get a full refund.
#TechInterviewCoaching
TechInterviewCoaching is a relatively small company with a curated roster of tech experts (at the time of writing, they have 19 coaches).
It previously only had one coach and offered its first session at $63. But now that it has expanded, it has shifted to a subscription-based payment method, starting at $200 per month. This includes 1 free session, 1 60-minute coaching session, and unlimited Q&A with the coach for the entire month. If you get the other tiers, you get volume discounts (for example, $350 per month gets you 2 60-minute sessions).
It does offer a 100% money-back guarantee, so if you’re not satisfied, you can get a refund, no questions asked.
5.4. Best Interviewing.io alternatives for engineers↑
#InterviewKickstart
Interview Kickstart is an online platform that offers comprehensive tech interview prep courses. They offer 18 different courses for key roles in tech, including various domains in engineering, tech management, data, and systems.
Each course program will include a live or self-paced course, mock interview sessions, placement assistance, a visa guide, unlimited coaching, and other services. The fastest program is less than 2 months. Before enrolling, you’ll have to join a webinar to learn more about their offerings and the cost.
Interview Kickstart does not offer single mock interview sessions, so it’s a good option only if you have the time and money.

#IGotAnOffer
IGotAnOffer has hundreds of engineering coaches from FAANG and other top tech companies. They represent many engineering roles, from software engineers, data engineers, site reliability engineers, and more. If you’re an engineer transitioning into a managerial role, you’ll find expert coaches who’ve been on that track as well.
These experts can give you inside insights into how to get and then ace your interviews at your target role and companies. They’ll help you familiarize yourself with the format of interviews, so there won’t be surprises in your actual interview.
The pricing is considerably lower compared to Interviewing.io, but the choice is much wider. Unlike with Interview Kickstart, you don’t need to pay for a whole interview prep course.
#AlgoExpert
AlgoExpert is a coding interview practice platform with a curated list of coding questions, organized by topic, letting you systematically build skills in arrays, trees, dynamic programming, and more.
It also offers mock interviews with a friend or a random user to simulate real interviews, giving you a taste of timing pressure and live coding expectations.
While its library is not as extensive as Leetcode, what works really well is its structure and clarity. Videos are consistent, the platform has an online IDE with test cases, and the layout makes it easy to focus on weak areas. If you learn better by seeing problems solved and explained, this is a solid supplement to raw problem grinding.
Check out our list of the best coding interview sites for more options.
#DesignGurus
DesignGurus is an online platform providing courses and interview preparation for software engineers, specializing in system design and coding interviews.
DesignGurus helps you prepare for system design interviews by focusing on large, real-world systems. It’s designed for those who have already covered the basics and want something more advanced for their interview preparation.
It’s not the cheapest option and, unlike IGotAnOffer, you can’t filter for interviewers who’ve worked at your target company at the same basic price. But with its reputation for advanced system design practice, it’s a platform worth checking out if you don’t mind the price.
Check out our list of the best system design mock interview platforms for more options.
5.5 Best Interviewing.io alternatives for product managers↑
#RocketBlocks
RocketBlocks is an online interview prep platform for candidates in product management, consulting, product marketing, and strategy & business operations. It is a subscription-based platform. You can opt for a monthly subscription or an annual pass and get access to their drills and concept reviews. To book a 1-on-1 coaching session, you’ll have to pay per hour on top of your subscription fee. You do have the option to choose based on your budget as they have 3 tiers.
You won’t find too many ratings and reviews of their services, though there are several verified testimonials on their website, and they have been recommended on some online forums.
#IGotAnOffer
IGotAnOffer has many expert PM coaches from FAANG and other top tech companies. These coaches are best equipped to give you inside information on how to get and ace your PM interview at your target company. When you book a coach, you can tell them what kind of PM interview questions you want to focus on: product design, product strategy, leadership, etc.
Apart from helping you practice your interview skills, they’ll familiarize you with the format of interviews, so there won’t be surprises on your actual interview.
The pricing is considerably lower compared to Interviewing.io, but the choice is much wider. Unlike with RocketBlocks, you don’t need to sign up for a monthly subscription.

5.6 Best Interviewing.io alternatives for fresh graduates↑
#MeetAPro
MeetAPro is a relatively new mock interview website. Based on its profile, it intends to be a platform for different professional virtual services. But for now, it mainly hosts mock interviews in information technology, finance, and medical industries.
What makes it unique is that you can browse the mock interview sessions based on subject matter and level. So if you’re a fresh graduate or an intern, you can easily find specific sessions tailored to your requirements. Usually, sessions aimed at fresh graduates will be at a lower price point.
#Pramp
Pramp is a website recently acquired by Exponent where you can schedule mock interviews with peers. Unlike Interviewing.io, which is recommended for engineers with some interview experience, Pramp is a great place for beginners because it’s free for five sessions per month. If you need more, you'll need to subscribe to Exponent.
Just like Interviewing.io, you can’t choose who you’ll have your peer mock session with. Based on the information you give at sign-up, Pramp will match you with the best peer. If you want to use its platform to practice with a friend, you can use the “invite session” feature.
6. Interviewing.io FAQs↑
If we did a good job writing this article, you should have found something in the list above that responds to your specific needs better than Interviewing.io.
If you didn’t, it might be that Interviewing.io is the best fit for you after all. Particularly if you’re looking for a mock interview website that offers anonymity and you can afford to wait to get an invite to sign up.
To help you make your final decision, let’s cover the Interviewing.io basics.
6.1 What is Interviewing.io?
Interviewing.io is an online platform that specializes in offering mock interviews for tech candidates. The quality of its coaches tends to be very high (they will have worked at Google, Amazon, etc.) Interestingly, it offers total anonymity by using voice interviews only (no video), which some users prefer.
Another aspect of Interviewing.io is that if you perform well enough in your mock interviews, you might get referred to an interview for an actual position at a top tech company.
6.2 Is Interviewing.io any good?
Yes, Interviewing.io is generally considered to be a good service, judging by reviews and testimonials of users on forums and on the website itself.
5.3 Who is the founder of Interviewing.io?
Interviewing.io was founded by a small group of engineers in San Francisco. One of its co-founders and current CEO, Aline Lerner, was the one to come up with the idea of an anonymous technical interview website.
After seeing companies place huge value on pedigree when hiring engineers, Lerner ran an experiment showing anonymous resumes to hiring managers and recruiters. When they couldn’t decide which of the anonymous candidates was a good hire, she realized that her hunch was right: pedigree isn’t a good basis for hiring engineers.
With Interviewing.io, their goal is to help talented engineers from all backgrounds improve their interviewing skills and get noticed by top companies based on their talent and skills, regardless of their pedigree.
6.4 Who are Interviewing.io’s competitors?
Other competitors to Interviewing.io that we haven't included in this article would be:
- TopCoding.io. This platform offers technical upskilling services specifically for software engineers. It doesn’t just offer coaching; it also has courses to help engineers get better at interviewing.
- DevInterview.io. This isn’t necessarily a mock interview coaching website. Rather, it’s a subscription-based service covering a “carefully curated catalog of interview essentials” for several tech topics.
7. Interviewing.io Review Conclusion
Interviewing.io is a good tech interview coaching platform, relatively well-priced and full of interesting and experienced people offering their expertise.
But is it the best option for you? Only you can decide that, although hopefully in this article we’ve helped you make a more informed decision.
