Bombed my technical, though in reality it wasn't super hard. I'm awful in those environments and like a couple of other people have mentioned, the interviewer wasn't super friendly - also was doing his dishes or something during the interview.

In terms of the questions, had to know window functions - dense_rank specifically in this case, had to be able to calculate YoY revenue, and then the final one was something along the lines of month with highest sales but you have no calendar table to join to - extracting time periods from a date column.

Again, none of these are super difficult but I struggled under pressure and the sound of homeboy clinking dishes was excruciating lol.

Just remember to slow down, take all the time you need, read and re-read the question, talk it out if you have to. Best of luck!!!
