Two rounds of interviews, 1st round screening -- delete a node from a linked list -- find the 1st missing number -- padding Did not do smoothly since still in working mode, but answered all. In fact, the interviewer's answer for padding is wrong. 2nd round the guy just say upfront the interview won't continue if 1st hour does not go well. To implement a generic stack API (create, push/pop), we discussed some technical details while I implemented the stack api. After I finished, he said sorry. Unlike others, i did not feel shocked though I don't know why. It saved the time of both of us if chemistry does not match.

Pretty good, not too complicated, was comfortable. Mostly LC questions, and was easy enough that you should be able to do it after doing NC150. good luck for the interview!
