Meta Data Scientist, Analytics interview questions

I initially gotten a link to schedule the call. Yet, I accidentally entered a typo in my number and emailed hr immediately. However, the hr did not reply until the time of the scheduled interview and gave me a bluejeans link which require me to download the app at the moment. Overall the questions were not difficult, but having to download an app at the last minute makes the experience not as good.

1. HR screen call; 2. 1st round interview: case + SQL; 3. final round: case + probability. The HR was very helpful along the way and responds very quickly. Usually get results within 2 days of interview.
