Interviewed twice, process has changed, but misleading information remains. They say that you don't need to be an expert in C/C++ but only ask low level C questions, not suitable if you are coming from a different language or not a recent CS graduate. They say you don't need to be an expert but also that you need to be very prepared. It's contradictory statements like this, plus pushy recruiters that make for a terrible and confusing experience. They'll say to take time to prepare, but then ask you to meet their hiring timeline. The new strategy is to e-mail candidates a wall of text with needless and exhaustive amounts of information. The work must be very tedious and annoying if the first level of screening is to put up with the recruiting process itself.

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!
