I had a long process of 8 interviews. Some of them were technical and some were with emphasis on leadership. My overall impression is that the hiring process is tough and I do not recommend others to apply for the role. At the end I just received some generic email after spending 9 hours in total.

1st round with HR - asked about my experiences and expectations etc - interview went well. 2nd round with senior engineering manager - asked few behavioral questions and few high level architecture questions - interview went well. 3rd round - 1 medium level coding question and 2 system design questions - interview according to me went very and interviewer said wish you good luck for next rounds which is positive for sure. I successfully solved coding question in python on 3rd attempt, gave 3 alternative solutions for one of system design problems. Interview went well as per me. There was one guy who was taking interview and there was another guy who was not talking at all. Next day I got email not moving forward with the profile. I asked for constructive feedback HR said it's against policy. I believe they are just doing interviews for some GC perm requirements of some employee in their organization. Overall not worth spending any time giving interview with this company.
