I applied online via LinkedIn.

I received a call from HR within a couple of days.

I was called for a F2F interview on Saturday. The interview process took over a week.

There were three questions related to shell scripting. I solved them, but the interviewer left after 10 minutes. After some time, HR came and told me to keep the papers on his desk when I was done.

Summary:

1. Poorly managed by HR/interviewer. I was told there would be a couple of technical rounds, but there was just one technical test, and the interviewer did not ask me to explain the logic.
2. No update from HR. After sending a couple of emails, I received an email stating the feedback was not positive.
3. It seems the interviewer was only interested in "Google" answers to the questions he asked. I cross-verified the logic of all three shell scripting questions, and it was correct (apart from some syntax errors).

Questions like printing a list of Unix processes with greater than certain CPU usage.
