I have very specific technical questions such as, describe the process an authentication frame makes in a network. Other tough question included behavioral questions such as, describe a time you disagreed with your manager and how did you handle it. These might seem standard but in the setting it was fairly intimidating. I left thinking I did not have the job and even threw up when I got back to my hotel room. I subsequently found out that all 20+ of us that were going through the process had already been hired and they were just determining which group you would work for.
