I applied online. The process took 2 weeks. I interviewed at Deloitte (Amberes) in Jan 2013
Interview
The interview process was relatively casual. They were looking for a person with IT knowledge but also some business knowledge (finance). The interviewer could not give a specific example of what my job function would entitle so I did not return for the second round.
imho I think they were just looking for people but were unable to give specific jobs because they didn't know yet. The person who interview me was a bit into himself. Not to say A LOT
I applied through an employee referral. The process took 4 weeks. I interviewed at Deloitte (Bengaluru) in May 2012
Interview
There were 4 rounds, first was telephonic, second was also telephonic, 3rd was face to face technical, 4th was HR round cum english assessment test. Since it was a technical role for which i was interviewing, there weren't many behavioral questions to begin with. But later stages did include english test, personality test and behavioral questions as well.
2 Rounds - Case Solving and Behavioral. The case was about a cloud versus on-premise deployment scenario. Make sure you ask the right questions. Details will be slowly revealed after the right questions are asked. Treat the interviewer as if he/she is the client. Assume you are the representative of Deloitte.
