Received random interviews which mostly didn't relate to the position that I was being interviewed. Talked to managers about some targeted pdf attack that they received and how I would defend against it if the opportunity cost was infinite dollars for the attack. At one point I was abandoned in a break/lunch room for an hour for me to entertain myself with my phone. Someone found me eventually.

First meeting with recruiter collected all information. then meeting scheduled with Hiring Manager: Asked questions from the job description but it was vague in which domain they were looking for.
