OA was on mental math, probability, and geometry. You need to answer the questions extremely quickly. Make sure you are submitting your answers correctly as the software is a little awkward.
Quite hard, few probability questions but they did give hints
Interviewer was nice, hour long interview with mostly technical questions and a few behavioral questions (tell me about yourself)...
The interviewer said there were a couple of rounds to get the winternship role
Only did the OA, got questions such as estimating the Arc length of sin(x) from 0 to pi. Is rapid fire, with ~20 mins for 15 of these difficult questions.
