Frequently asked questions

What does upgrading to premium get me?

The full course gives you the step by step guide and frameworks on how to ace the data science interview. We thoroughly go through multiple data science concepts including product intuition, sql, machine learning, and more. Additionally our question bank provides solutions and mock interviews for over 200+ interview questions and access to over 400+ exclusive interview questions with more added every single week.

You'll also be able to access our SQL, Python and R editors for practice, recently asked interview questions with discussions and company tags, and a community of data scientists to practice peer to peer mock interviews with.

Do you have questions from Facebook / Google / Amazon / Microsoft?

Yes, every single question is curated from an actual data science, machine learning engineering, or data analytics interview from top tech companies. We spend hours crafting each solution to make sure it's easy to understand and conceptualize.

Where do you get your questions from?

We source our questions from various sources, including submissions from real candidates who have attended interviews, as well as scraping from a range of data sources.

Are your questions accurate and recent?

Our questions are all verified by recent interview candidates, to make sure they are real questions being asked in interviews. Questions are sortable by recency date, so you can see which questions are still being asked in recent days.

Should I still sign up if I want a job as a Data Analyst / Business Analyst / Machine Learning Engineer / Data Engineer instead?

Absolutely! All of the various data positions require learning and practicing overlapping concepts and interview questions. For example, some knowledge of SQL and machine learning is generally needed for all data positions. Each job requires a spectrum of knowledge from the more statistical side of product and business analytics to the more engineering side of data engineering and machine learning. Additionally, we work on classifying interview questions asked by different companies and positions on Interview Query. That way if you're preparing for a specific role, you can filter by position titles.

How can I learn more about your coaches and how the coaching program works?

Check out our list of coaches here and more details on how we provide one on one mentorship to help you land your dream job.

How many take-home challenges do you have?

We have over 30+ take-home challenges from tech companies such as Airbnb, Uber, and Lyft with exercises ranging from SQL and analytics to model building.

Do the take-home challenges come with solutions?

About half of the challenges come with example solutions from our network of data scientists. All of them have example datasets to work with.

Can't I get this stuff for free?

you definitely can find a lot of the material online, but most of it is not well organized. Instead our job is to provide a structured way of learning data science and teaching you how to ace interviews with leveled practice. We go through the effort of explaining the solution to the most relevant interview questions, compiling the challenges from recent interviewees, and creating strategy guides to make sure you are expertly prepared for all of your upcoming interviews!

Is it really worth the money?

We think so! $200+ is about two hours of the work day when a data science job salary averages over $130K!

Is there a free trial for the premium subscription?

With the free account, you get a preview to our data science interview course, interview questions, 5 free code editor runs, and three solutions that you can view for free. It’s a great way to test out our platform before committing to it.
