Unscripted Interview Videos

The Cracking the Coding Interview Videos are unscripted videos showing you what happens in a real technical interview. Watch Gayle L. McDowell, the founder and CEO of CareerCup, interview a candidate, just like she did over 100 times for big companies like Google and Microsoft. Watch how candidates face a new problem, dissect it, and code it on the white board.

What do we mean by "unscripted?"

Exactly what it sounds like. The candidates were not told what to say when, or how to solve the question. They didn't even know what they would be asked until the cameras were rolling! In other words, what you are watching is 100% true-to-life.

These videos will:

  • Expose you to what a real Google / Microsoft / Amazon interview is like.
  • Show you how to handle questions when you don't know the answer.
  • Show you, via mid-video pop-ups, what is going well and what the interviewer is thinking about.
  • Teach you what Google, Microsoft and Amazon look for in an interview.



Full Interview with Danny

The Full Interview Video is a video that shows you what an interview is like, from start to end. The contents include:
- Overview of what companies like Google, Microsoft and Amazon look for.
- Discussion of the candidate's resume, to show you how to discuss your resume and what you're likely to be asked.
- Two coding and algorithms questions (including white-boarding coding). This candidate didn't know the answers, so you can learn how to handle this situation.
