Interview process
The process went well, and the interviews did not seem to be very difficult. The process began with a tech screen on MS Teams (video call with the recruiter). Tech Screen was a 45 minute interview that included SQL and Python questions.
AB Testing and Stats interview involved requiring knowledge about 2-sided marketplaces. For Stats, basics were also questions - what is alpha? what are type 1 and type 2 errors?
Last round was conducted by the HM, mostly related to behavioral questions.

Tips from the candidate
Get SQL and python basics strong - be fast and explain your work.
A/B Testing and product cases will need you to articulate your thoughts well.

The interviewers were helpful and friendly. Even when i thought i might have lost the answer, they guided me to think through it and was able to give the answer correctly.
