The recruiting process was good until the final onsite interview. HR was extremely reliable and followed through the entire way. The same can't be said about the actual interview... Interviewers were unprofessional and didn't introduce themselves. Was told to prepare for a systems design interview and instead, they asked me some unclear library-based question which no-one could prepare for. Clarifying questions that I asked were not replied to or were done so in a way that left me even more confused. Total waste of time - would've declined the offer even if it was made. I haven't experienced too many technical interviews but this took the cake for the worst.
