The panel interview was on-site and included mostly managers.

There were a total of 7 interviewers in the panel for the staff software engineer position.

The phone screen was basic and quick.

Initially, they asked security-related questions, and all went well.

Then, they asked me to implement a very basic data structure on the whiteboard. All seven interviewers watched what I was writing. They were quick to point out mistakes, even before I finished writing. It was an easy implementation, but having all seven interviewers watching and pointing out mistakes continuously made me nervous.
