ATYETI Interview Questions, Process, and Tips

Interview preparation tips for other job seekers - Please avoid this company. They will simply waste your time.
I interviewed for the role of Senior Java developer for one of their clients : Morgan Stanley. First round was telephonic round conducted by Atyeti and I was asked basic Java questions. On clearing round 1, I was assigned a 90 mins hackerank test from Morgan Stanley. On clearing hackerrank test there were another 3 rounds which were directly conducted by Morgan Stanley. In the final round I received confirmation that I had been shortlisted and also had a salary and joining date discussion with Atyeti h.r..Was also asked to submit my relevant documents which I did. However there was no response even after 2.5 weeks and finally when I reached out multiple times, I was informed that the position was put on hold by Morgan Stanley.
Completely wasted around 35-40 days on the entire process, not to mention the false assurance of confirmation.
