Pretty straightforward -- tech screening from a recruiter over the phone, followed by a more in-depth tech screen from a senior systems administrator, also over the phone. Later I did an in-person interview with a manager, a sysadmin, and a senior sysadmin. A few days later I received and accepted an offer and negotiated a start date. The interview questions were Linux shell basics (sed, awk, cut, grep, uniq, etc), virtual hosting in Apache, DNS, networking, etc.

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 :).
