was contacted by recruiter saying they were interested in talking to me about network system engineer position. Went in, found people from 3 groups going to interview me. 3 out of 4 interview sessions were conducted by two people at same time, like mini panel. They most asked skill or area that they would need out of me for their need. I have been doing SQA in networking field, they asked me to design test cases for the scenarios (simpler or more complex ones ) they gave on whiteboard or paper, then asked a lot of automation and perl, and even had to explain a hard-to-read perl script on a paper they brought in. Next day, got email for second around of interview with one of group , not sure what would be next.
