I recruited through my university in 2017 and the process lasted about 10+ weeks . The process was very unorganized, I would get notified sometimes a day or two before I had an interview. Interviews would also go significantly over time (ex: scheduled 45mins, actual 1.5 hours). This company definitely thinks very highly of themselves and has winning product so I understand they want to really vet their candidates to ensure there is a fit. That being said a 3-4 month process is unnecessary. After multiple interviews (3 months) I did not hear back that I was unsuccessful until 4+ weeks after my final interview (I followed up multiple times). I did multiple on campus recruiting interviews (some successful some not) and this was by far the most negative.
