Interview Query

Facebook Data Scientist | October 2018

Company: Facebook

Position: Data Scientist

Location: San Francisco Bay Area, CA

Level: nan

Outcome: Accepted Offer

How was the interview process? What was it like?

I did well because they gave me an offer, they prepared interviewees quite well

What technical questions were asked?

Product Metrics and Measurement, SQL / Pandas, Probability, Statistics & AB Testing, Business Case and Estimation

What was one of your solutions?

I started by asking about the data generation process (how confident are we in the logging, etc). Then I broke down the data into a country by country analysis, and looked for temporal trends there, developed some hypothesis that we discussed further. there were a lot of questions about how to design an experiment to validate my assumptions, which were either a/b tests to solutions I came up with or further analyses.
