I applied online. The process took 4 weeks. I interviewed at IBM (Los Angeles, CA) in Mar 2019
Interview
Everything went as planned. I had a good time talking to my interviewer, the problems that they asked were very much in line with what I expected. Unfortunately, in the end I didn't get an offer, but will try again in the future.
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.
