Laughable SQL round administered by a “senior” data engineer with no hands on experience with Spark or open table formats. Nitpicky questions during a “pair programming” exercise where the assumption is that you know nothing (I’m a long tenured FAANG employee). Read on if you’re curious, but generally just stay away.

Reading a solution is not the same as writing one
Every engineer who has frozen on a query they had read a dozen times knows the gap. The only preparation that closes it is producing the answer yourself, under time, before the interview does it for you

Dedup, sessionization, top-N-per-group, slowly-changing dimensions, partition tricks. Writing the shapes by hand turns the unfamiliar into pattern recognition
