SecureKey intern: operations security engineer interview questions

I was interviewed by the senior security engineer and the director of service engineering. I sent an unsolicited application, as the company welcomes them (see the career section in their website). Questions were revolving around network (TCP layer model) and infrastructure security (firewalls, vpn, identity verification in TLS, how to use pentest tools etc..). The interview took less than an hour, and I receive an offer the next day.
