It was Quite complicated and lengthy process. It took us over 7 months for it to complete and gave several rounds of interview. Feedback on each round is shared after 1-2 weeks. It's hectic and still if you get rejected it really hurts. I would suggest look for much better opportunities out there instead of wasting so much time. The selection rate is almost 5% and rest others only get rejected. From personal experience, sharing that they hide so many things initially then tell you later.
