Meta Data Science interview questions

no HR round , direct 45 min screening. The person was grumpy, sad but asked so many question. Dint even ask about my background. questions were so mechanical. asked abt a design experiment. gosh! what guardrail metrics would you consider.

I got mail for data scientist- product analytics from recruiter. Recruiter was very responsive. Next was Coding round, which is based on the language you, when you speak with recruiter and you cannot change that after scheduling.
