Interview

Filled up the online application and got an email scheduling a phone interview. They asked probability and statistics questions such as coin flipping, dice rolling, etc. and also some mental math questions. Overall the questions weren't very difficult but since you couldn't use a pen and paper it was a lil tricky.
