Data scientist mock interview service. Practice 1-on-1 with DSs from Google, Amazon, etc.

You can structure your preparation for a data science interview across five steps:

• Get familiar with the interview process at your company. 
• Read up on the company culture and current challenges. 
• Find out what types of questions you can expect at your company (probably a mix of Statistics and Machine Learning, Coding, Behavioral and Product Sense). 
• Practice answering questions on your own. 
• Finally, do mock interviews to get expert feedback and increase your chances of landing an offer.

Take a look at our data science interview prep guide for all the information you need to get started.

Practicing mock interviews, as a data scientist or another position, is super easy on our platform. You simply buy as many mock interview sessions as you’d like, then browse our interview coaches and schedule sessions with them.

Each session lasts 1h. At the time of the session, you’ll login to a Zoom call to meet your interview coach. They’ll confirm the objectives of the session with you, give you a mock interview (45mins), followed by feedback (15mins). You’ll be in touch with your coach over email before and after the session so you can ask any questions you have.

Data science interviews are challenging and often complex, and the interview success rates at top tech companies are low. However, with the right preparation you can greatly increase your chances of acing your data science interviews and landing an offer.

If you’re looking to practice mock interviews with other candidates, we recommend checking our list of best mock interview websites which includes free peer-to-peer options. However, while doing mock interviews with peers can be useful to get started, we recommend practicing with actual ex-interviewers, if you can afford the extra investment. They’ll be able to provide you with highly accurate and actionable feedback. This is what our coaches specialize in.

Yes, once you’ve purchased your mock interview sessions you can schedule them with any coach on our team.

Yes, unused mock interview sessions can be refunded within 30 days of getting purchased. After 30 days the sessions cannot be refunded anymore, but you can still use them at any point in the future.

If you do get a refund it will be corrected for the discount you initially got. As an example, imagine you have purchased 10 sessions, and paid 10 x $129 = $1,290. If you end up only using 5 sessions, we will refund you the difference between what you have paid ($1,290), and what you would have paid had you purchased 5 sessions (5 x $139 = $695). So in this specific example we would refund: $1,290 - $695 = $595.

You can request a refund for your unused sessions directly from the order tab in your account.

There is no time limit to use the mock interview sessions. You can purchase them now and use them whenever you like.

Once you've purchased your sessions you'll have access to our mock interview scheduling system. You'll be able to pick a coach and select an available time slot in their calendar. Coaches require 24h notice for the sessions. So if you purchase today you could start with your first session as early as tomorrow. When you book a coach you'll also be able to let them know what you'd like to focus on for your session (e.g. product strategy, product design etc.) and they'll be able to help with that.

Your mock interview session is tailored to you. Your coach will work with you in advance of the session to decide what you will cover during the hour. Most of the candidates who work with us use this time to do a full mock interview but you could use it instead as an hour of coaching and advice.

When booking a coach you’ll be given the opportunity to specify what companies you’re interviewing with (e.g. Google, Facebook, etc.) and what question types you would like to focus on. If you don’t know the answer to these questions yet that’s completely fine – your coach will be here to guide you.

Mock interview sessions can be cancelled and rescheduled for free by giving us more than 24h notice. In other words, if you decide you don’t need the session anymore and tell us more than 24h in advance it will be eligible for a refund as an "unused" session. Or if you decided that you want to do the session at another time and tell us more than 24h in advance we will reschedule it for free.

If you fail to attend a mock interview session, or are more than 15mins late, the session will be considered a "no show" and it will count as having been used.
