FRAMEWORK

The most difficult interview in tech

Helpfully, Jane Street has published a mock technical interview to show candidates what to expect.

What she did really well in this interview…
(and what you should do in every technical interview)

  • Clarified early (and repeatedly)
    She kept asking questions until she fully understood the rules, so she didn’t waste time solving the wrong thing.

  • Thought out loud
    She explains step-by-step, helping the interviewer to follow her logic AND give helpful hints

  • Made it a discussion
    It felt collaborative, not like she was being “tested”.

  • Broke big problems into smaller ones`

    She tried simple strategies, tested and compared them, and improved

  • Was comfortable being wrong or unsure & adapting her answers
    When something wasn’t clear, or she made a mistake, she was open about it.

  • Had a friendly and fun approach
    She was calm, polite, and easy to work with

Key Takeaway
Notice that in the feedback section at the end of the video, the interviewer doesn’t focus on whether her answer is “correct”.
He focuses on her communication and problem-solving skills.

These are the skills you should be preparing for!
