Meta Data Engineer interview questions

Interview question was about constructing a power set of N elements. I was pretty familiar and wanted to make a closed form version that would be faster. Interviewer's internet dropped the call partway through the call, got impatient soon after reconnecting, then ended the interview abruptly. Never heard back.

Reached out by recruiter, 15 min prescreen on 5 SQL and 5 Python questions to move on to the next round. Still undergoing the interview process with the company as of now.
