I applied through college or university. The process took 2 weeks. I interviewed at IBM (Troy, NY) in Nov 2012
Interview
On campus interview followed by a phone interview. The campus interview was roughly 30 min. We were give a set of data prior to the interview. At the interview we were asked about the data, and what we could infer. In addition, there were skills based questions gauging our understanding of the foundation of electronics. Overall, the interview wasn't to nerve raking, and some of the puzzle questions were actually a bit of fun.
Interview questions [1]
Question 1
A mixture of technical and team work based questions. We were given a set of data, and asked to make sense of it.
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.
