I applied through an employee referral. I interviewed at IBM (New York, NY) in Jan 2017
Interview
Straightforward process with senior team members in the department. They were able to come to a quick decision following the interviews and did not waste time. Every conversation had relevant questions asked and did not waste time with unnecessary filtering problems.
Interview questions [1]
Question 1
Walk through previous experiences in detail for relevant overlap
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.
