How was the interview process? What was it like?
Phone Screen with recruiter was very easy. The technical interview after that was very difficult and consisted of a Product Case and a very difficult SQL question. The onsite interview went fairly smoothly and consisted of 4, 30 minute interviews. I felt I did pretty well in the interview but did not receive an offer
What technical questions were asked?
Probability, SQL / Pandas, Business Case and Estimation, Statistics & AB Testing, Product Metrics and Measurement
What was one of your solutions?
1. Wasn't sure on this one, got stuck
2. Find restaurants in the user's location that are similar to page likes and that their friends also like and recommend these. Perform A/B testing to see if the recommendation algorithm results in more clicks or likes on restaurant pages
