It all depends upon the service line and kind of profile you have got a call for. If it is for a Management Process, then there will be a initial scanning by HR and the India Business Manager. They will probably go with 4-5 profile and will select 2-3 out of it. They will have a initial discussion probably over a phone and will forward the eligible case to US. A Telephonic interview will be taken on US. This going to be the most critical. Most of the time it is 1:1 but it can also be taken by a Panel. It the person is selected, then HR may call the candidate to office for a face to face meeting. This is more of a formalities unless there is a exceptional case. Just to add, there is a communication test that a candidate has to pass, as Deloitte stress a lot on Communication. It is more like a IELTS or any other recognised English Test. In a week or so, they will make the final decision and will share the news with the Candidate.
