Joined under graduate trainee programme. The process takes around 2 months ( Submitted application in September, interview in October, confirmation in November).
Did online reasoning test when applying the job. I was required to take only numerical reasonings back in 2008 but heard that the subsequent years candidates were required to take verbal reasonings too.
Called up by HR for interview 2 weeks later.
Went through 2 sessions yet 4 rounds of interview. The first session was interviewed by two team managers (VP level). Two weeks later, the second session was interviewed by three D level managers, 3 rounds back-to-back (30min each). Had on-site numerical paper test (1 hour) after the back-to-back interview.
