3 rounds of interview, 2 technical ,1 managerial. 1st technical round would test your basics,2nd one will be based on your profile. More of scenario based questions will be asked, multiple streams like R&S, Security, should have good knowledge on VPN's.

I had a phone screen with the account manager for the client. Then I had 3 phone interviews with the client, the first two in rapid succession, then the job looked like it would be canceled, but a few months late they called me back and asked me if i was still interested.
