I applied online. I interviewed at Meta in Apr 2019
Interview
I had interviewed with Facebook for university grad data scientist position. I couldn't clear the SQL round and got rejected. I had got an email from the recruiter and was asked to fill some questions. After I completed that a 15 mins round with HR was scheduled. He asked me some SQL questions and one hypothetical case regarding my favorite facebook product. (Don't take this round very lightly I have heard people getting rejected from this round as well). After that round, I was scheduled a skype round with the Data Science Manager which was divided into SQL query and product based questions. He gave me SQL queries to write, my queries were perfect but I didn't write an optimize query which was the problem. Don't write big queries try to write optimized queries. The product related questions were quite straight forward and I don't think they are looking for specific answers. So one can just practice some questions like how will you test the success of a product? Or What changes will you propose to make the product better, etc. I was asked the usage of the status updates has decreased so how will you test that thing? Overall I believe the SQL query should be really good to clear this round.
Interview questions [1]
Question 1
How will you investigate the decrease of involvement in any of the facebook products?
Conversation with recruiter in email. Technical screening round where they ask about SQL and product sense. Onsite-Loop with four rounds. They ask about SQL, Product Sense, Statistics, Behavioural questions. The difficulty is average.
The technical round kicked off with a design question about A/B testing for Facebook Reels, which I found engaging. Then, I tackled a SQL query on user comments and how to account for novelty effects in ongoing experiments. Thankfully, I had prepared with the company-specific questions on PracHub, and it made a real difference in my confidence. The entire process felt smooth, and after some behavioral questions, I received an offer that I happily accepted.
