I interviewed at Accenture, process was supposed to last 3 weeks and lasted 3 months for just 3 interviews, and no communication between each interview. I received very positive feedback after the last interview but apparently, they decided not to recruit anybody externally. Companies should be allowed to run this kind of bogus process wasting time, energy, and illusions of candidates. Really a bad experience.

No idea. Applied online, sorted a date with a recruiter. They then rescheduled that date to two weeks in the future. I sat in Teams waiting room for 20 mins and interviewer didn't turn up. Nothing from recruitment.
