Online application, shortlisted for an OA. 2 medium question and 1 hard. The hard one requires you to build an avl tree to meet nlgn time complexity, insane! Otherwise u got like 7/10, and they will fail you.

Entrevista
In the screening interview, the engineer taking the interview was really rude. He started flaming my Uni out of random, indicating that most of the graduates were from "Stanford/Berkeley", then started to flame my experiences. I don't think, I was asked one question which was relevant to my experience or the role.

Entrevista
The process was pretty standard. I received a Hackerrank OA followed by a hiring manager round. Another leetcode style and system design round followed by a final behavioural round. All the feedback was positive but after the last round, the manager called me and said they were going in a different direction and said he twasn't allowed to give any feedback.
It was long and had many stages. Phone interview then technical then behavioral again at the end. Know both design and algorithmic problem solving. Overall felt decently challenged but still possible.
