Very professional, what you would expect from a top tech company. Thoroughly impressed by the professionalism of the engineers who conducted the interview, as well as the entire process in general. Be enthusiastic about projects you have done, and be honest when conveying your technical knowledge and background. They recognize that and appreciate it. Make sure you can't speak to anything on your resume, because they will ask.

Three weeks after applying, I was invited to a 30-minute screening interview for this Friday. However, only 20 minutes before the scheduled start time, they requested to reschedule to Monday. Given that I had already rearranged my day to accommodate the original meeting, I chose to withdraw my application out of respect for my own time.
