2 back-to-back first round interviews on-campus - 1 was behavioral, 1 was technical (asked basic questions about enterprise security, etc.). Notified that I was invited to second round about 2 weeks after first. Second round was an office visit to Oak Brook - included bowling pre-night with employees from the firm. Second day was an office tour and lunch with employees in the units we were interviewing with. There was no interview during the second round, just office visit. Received offer about 2 weeks after visit.
