I applied through university. The process took 1 day. I interviewed at IBM (Singapore) in Aug 2011
Interview
Short and brief as I was an intern. Just be honest with the interviewer and you will make it in. They want to know about your personality and whether you are willing to learn.
First round was a case interview and final round was a behavioral interview with a more senior member of the team. Each interview was 45 minutes with one member from the team.
There was only 1 round of interview. Heard from recruiter 1 month after submitted application. Interview was 1 hour and did not seem structured at all; it went over a mix of technical and behavioral topics.
First stage of CV application, followed by an in-person assessment centre, then final interview with hiring manager in person in Southbank London office. Many assessment centres were running throughout 2017 when i applied.
