Once you get through the phone interviews they bring a group of candidates in and you are interviewed with multiple rounds with several sessions. 10-30 candidates are interviewed together. Overall it is a pretty easy process, just a long day.

Completely unprofessional. Was given interview in the morning. Day of interview I'm waiting for their call and the time they gave me passes. Ten minutes later they say they became too busy and need to reschedule. They said they would email me later to set something up. Never heard anything back. Complete waste of my time. Honestly tells me a lot about their company.
