I applied through a recruiter. The process took 4 weeks. I interviewed at Meta (Menlo Park, CA) in Feb 2019
Interview
A recruiter reached out to me to schedule a brief screening call. This was followed by:
1) a 45 minute first interview with a current employee on product sense and SQL;
2) a day onsite with 4 components:
1) product interview (can you reason about facebook's products?);
2) technical analysis (lots of SQL);
3) analytical (questions about AB testing and the properties of the binomial distribution);
4) applied data (general reasoning about data problems);
3) A follow-up SQL interview
Throughout the interview process, I realized that this was more of a business /product analyst role than a data science role, since the main focus was on SQL queries and stat101 probability questions (e.g. "what's the variance of the binomial distribution").
Interview questions [1]
Question 1
How would you explain a confidence interval to a business-person?
The process is systematic and HR is very helping. The questions are the same, you will want to talk about your assumption and communicate your thought process. The interviewer is also friendly. However, I think I didn't get the offer because of head count.
I applied through college or university. I interviewed at Meta
Interview
I got a phone screen for 15 mins from HR, walking through my resume and checking about my visa status. It is very easy and after that, we schedule for the next round for a technical screen.
