What does FB ask in their Data Science interview?

Technical - Heard pretty simple SQL

Business - Heard its interpreting results, knowing how to design an experiment, etc.

Stats - Heard its P value, significance, etc.? Feel like this is where im the weakest

Any insights on questions and how to answer these?

    My advice for the stats questions is to use stats terminology as much as you can when your answering the question ex “distribution”, “long tail”, “test of proportions”, “pooled standard error”. DM if you have questions. I didn’t pass but I’ll be happy to tell u wat not to do lol

    I have a call with recruiter next week, can I expect any questions apart from my background and resume?

      Yes they might ask u a simple product question ex how would measure the health of Instagram. They expect u to ask clarifying question to break down the problem then come up with a simple framework to solve it and talk about metrics etc.

    Did you get a phone interview or on-site ? They usually send emails with materials you need to prepare

  • Are for interviewing for product analytics, core, or infra? It seems like product analytics — that’s about it. I would say go through all the prep work and get a lot of sleep

      I only heard about product and core. What's infra, it's not talked about a lot here. How does the interview process differ?

      OP
      Analytics. And not sure how to answer the “designing of experiments” or statistical questions. Doesn’t seem like Leetcode has much for that
