Meta Data Science Intern interview questions

2 rounds with interviewer after email screen. straightforward, difficult but no surprises. The information/prep material given is quite accurate. - Requires good amount of analytical thinking, SQL and product case.

There was 2 parts: product-sense and SQL. In the product sense, I had to design an A/B experimentation for a recommendation in the UI. The interviewer was nice and asked me many open-ended questions such as "How would you design it?" or "How would you decide if you want to launch it"
