I applied through college or university. I interviewed at Meta
Interview
I submitted my CV in October 2018, then got an email from HR in late Oct. The first round is a 20 minutes call with HR talking about my motivations, why facebook and why data science. Then there were 2 rounds of 45 minutes video interview. The first is more techinical, with coding in SQL, combined with some product questions. The second is purely product sense and some quantitative questions.
I applied through a recruiter. The process took 4 weeks. I interviewed at Meta (San Francisco, CA) in Oct 2018
Interview
The interview process was very straight forward. It started with two case study analysis questions, and ended with a coding challenge using any programming language of choice. All questions were anchored around the same subject of segmenting users on the platform .
Interview questions [1]
Question 1
How can we find people on Facebook with multiple accounts?
Applied by a referral, had an HR pre-screen interview with some basic SQL concepts, and then did the phone interview with a Senior Data Scientist. It is a very normal process like any other tech firms.
