Question 1

How should I prepare for a system design interview?

Accepted Answer

System design interviews are a common part of the hiring process for mid- and senior-level engineering roles at companies like Google, Meta, and Amazon. They test your ability to design scalable, reliable systems and evaluate how you think about tradeoffs.

During the interview, you’ll typically be asked to design a real-world product, like YouTube, Instagram, or Google Maps. You’ll need to:

Clarify product requirements and constraints
Design a high-level system architecture using appropriate components (e.g. load balancers, databases, caches, queues)
Dive into specific areas such as data storage, APIs, or scaling strategies
Justify your decisions and walk through tradeoffs around cost, performance, and availability

To prepare, make sure to:

Review the architecture and use cases of common system components
Use a framework to structure your answers
Practice real system design questions from past interviews
Watch mock interviews to learn how experienced engineers approach problems and structure their answers
Do interview coaching with expert interviewers to get feedback and build confidence

Question 2

What does {{page.skill.name|add_article}} interview coach do?

Accepted Answer

{{page.skill.name|add_article, capitalize}} interview coach helps you practice real interviews so you can think on your feet—something you just can’t simulate alone or with a bot. They give expert feedback that friends or peers usually can’t, help you build confidence, and focus your prep on what really matters. The right coach will also bring company-specific insights and help you pick the best stories to tell in your behavioral interviews.

Here's a more detailed look at what {{page.skill.name|add_article}} interview coach can do for you:

Give you expert feedback: After conducting a mock interview with you, your coach will zoom in on your weaker areas and give you highly actionable, specific feedback that you can take away and use to improve your performance.
Help you prepare more efficiently: {{page.skill.name|add_article, capitalize}} interview coach can help you save weeks of unnecessary prep time by creating a study plan that cuts through the noise and helps you focus on the most important areas.
Increase your confidence: Studies have shown that around 93% of people feel nervous before a job interview. Unless you’re one of the 7% with ice in their veins, you’ll need to find a way to deal with nerves, remain calm, and project confidence. The more you practice something, the less stressful it should become, so mock interviews with a coach can really help reduce anxiety.
Give company-specific insights into the interview process: Too often, interview processes at large corporations are slow and rather opaque. Glassdoor.com is useful but has its limits. If you really want some insight from someone who’s been on the inside of the process, book {{page.skill.name|add_article}} interview coach who has run interviews at the company you’re interviewing for.
Help you tell the right stories: Your coach will tell you what interviewers really want to hear about, and will show you how to tell the most impactful stories.
Gauge whether you’re ready: Some candidates like to use interview coaching to test their readiness levels. They then adapt their interview preparation accordingly.
Help you structure your answers: Almost any answer you give in an interview should have a structure. For example, most people use the STAR method for answering behavioral questions (though we believe that the SPSIL method is better). An interview coach can show you the relevant answer frameworks that are relevant to your interviews.

Question 3

How will my {{page.skill.name}} interview coaching session work?

Accepted Answer

In a 1h mock interview session, you’ll spend 45 minutes being interviewed by your coach and they will give you feedback on your performance for 15 minutes. They will identify your weak points, give insightful, actionable advice on how to improve, and give you more confidence going into your real interviews.

In a more general preparation session, you can get your {{page.skill.name}} interview coach to help you structure your preparation, answer any questions you might have about your upcoming interview, and make more efficient use of your study time.

Question 4

How much does {{page.skill.name|add_article}} interview coach normally cost?

Accepted Answer

{{page.skill.name}} interview coaches normally cost over $200 per hour, and if they have experience at top companies you can easily pay $300 per hour or much more. It is sometimes possible to find coaches who charge lower rates, especially on sites like Fiverr, but they usually lack interviewer experience at top companies.

Various factors affect what you might pay for interview coaching:

The type and level of expertise the coach has and how specialized they are
How good the website is (e.g can you instantly schedule a coaching session or do you have to call?)
Level of seniority (for example, an exec {{page.skill.name}} coach will charge more than an entry-level {{page.skill.name}} coach)
Booking individual hours vs bulk buying
The coaching platform's 'take rate'
Whether it includes added services as well as the mock interview session

On our platform you can hire an experienced {{page.skill.name}} interview coach from just $100 per hour. This makes IGotAnOffer easily one of the most affordable interview coaching services around.

Question 5

How is practicing with {{page.skill.name|add_article}} interview coach different to doing mocks with a friend or peer?

Accepted Answer

Practicing with {{page.skill.name|add_article}} interview coach is a totally different experience from doing mocks with a friend or peer.

Our coaches have all conducted interviews at top companies, so they know exactly what interviewers are looking for. They won’t just say “that sounded good”, they’ll tell you why something worked or didn’t, and how to make your answers tighter, clearer, and more impactful.

Friends or peers might be smart, but they’re not calibrated. A coach will push you on the right things, find your weak points, and give you a realistic sense of how you'd perform in a real interview. Plus, they can help you build a plan, identify gaps in your prep, and flag blind spots you didn’t know you had.
