Very awkward and the interviewer was not prepared in the slightest. Reflected poorly on IBM. No comprehensive questions asked. It was a video interview, and the interviewer was sitting on his couch in pajamas. Never contacted me again, no call or email. Not a fan of the hiring process, and that it took 4 months to simply receive "no".
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.
