I applied through university. The process took 5 days. I interviewed at IBM (Kingston, ON) in Mar 2011
Interview
I actually interviewed with a number of teams. I was asked a range of types of questions: there were general personality questions to assess my fit within teams, but then there were other questions that probed my knowledge of computer science. Particularly: data structures (tress, maps, arrays, etc.), quality assurance techniques (black box testing, white box testing) to some basic concepts of C as well. The difficulty did range quite a bit too, from easy to challenging.
Interview questions [1]
Question 1
Asked me what would be a quick way to sort out duplicates from a series of strings.
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.
