I managed to get to the OA step of the interview. At the moment, I did not know how to solve the problems because I hadn't researched anything on DS&Algos; I had only applied passively. I was given a week between being told I had an OA interview and the five days to finish the OA. The OA is typically 70 minutes.
I have two questions.
One was a string manipulation problem (longest common prefix), and the other was an array problem (I can't remember exactly which one).
I'd say the first one was medium difficulty, and the second one was easy.
