I applied online. The process took 1 day. I interviewed at IBM (Warwick, West Midlands, England) in Jan 2015
Interview
I had an assessment day at IBM and found my experience a challenging but engaging experience. The day consisted of one on one interviews, a one-to-one presentation about what I knew and liked about IBM and few group assessment tasks that were overlooked by a panel of interviewers.
Interview questions [1]
Question 1
Which of the current projects that IBM is working on currently interest you the most and why?
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.
