they asked me basic commands in linux like cd, cp, rm. mv. top, vmstat, iostat, kill, pkill, uname, then briefly about FTP, DNS, NIS, kickstart, TFTP, after that questions on personality based like what is one thing do you want to change in your last company if you have a chance?, Did you do any mistake in the last job and how could you solve that?, how would you assist a customer who is angry on you., why do you think that you are a good fit for this position?.

4 Rounds of interviews, Which include online exams and virtual interviews. 1. online English grammar test- laptop camera should be on and you can not leave once you start. 2. Technical interview. It was a panel of 2 persons which test your techical skill for the role you applied {for me it was Linux} 3. Managerial round- this is a little difficult as they check your stability and long-term association with the organization. 4. HR round- It was fun as after clearing all the above interviews it was time for salary negotiation :).
