I applied through college or university. The process took 1 week. I interviewed at IBM (Chicago, IL) in Oct 2015
Interview
Applied through on-campus recruiting, scheduled interview with a guy who was actually substituting for another person who was not able to make it. The interview was relaxing, very conversational, he was very interested in my data analytical skills.
Interview questions [1]
Question 1
Tell me about a time that you used data to solve a problem
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.
