First screening followed by 3 technical rounds for 1 hr And then followed by Director round which is final round. 2 technical rounds are taken by Devops professional which ask automation and Devops related questions but one technical round is taken by infrastructure engineer who was asking only Linux admin questions In the end, I went till director round which is the last round and everything was good in that round but after that when I am asking for feedback on mail nobody responded. Anyways, you should have shown professional behavior by giving detailed feedback to candidate who went till last round and spent a lot of time .
