Company: Snap

Location: Los Angeles, CA

Role: Data Scientist

Level: Mid-Level

Outcome: Rejected

When did you have this interview?: Last Month

Interview process: 1 tech screen on SQL and basic manipulation python; 2nd tech screen: A/B test, probability, case question; onsite: 1 round with hm, 1 round with cross functional partner.

Outcome: went through onsite, but rejected without feedback.

Experience: overall positive experience, but shock at only 2 rounds for onsite. It seems to be very team specific and only met with team members besides one more person at cross functional team.

What kind of technical questions did you get asked?

  • If you are flipping a coin 1000 times, got 600 heads, how do you determine if this is a fair coin? Solution: sign test, confident interval.

  • Python: calculate retention rate 7 days after product launch.
