The process took 1 day. I interviewed at IBM in Jan 2008
Interview
This was just a first level interview during a Operations Research conference for their internal consulting group. The employers invited those interested in the positions to attend their session in the conference. The interview consisted of detailed questions on experience with databases and data mining. You interview with at least 2 employers during the conference. One interview was a little more technical, the other had just the basic interview questions.
Obviously a preferred site if you are very advanced in Operations Research, since you are at the conference. If you do not have a lot of experience on it, you are overshadowed by those whose degrees are solely on OR, or any applicable subject
Interview questions [1]
Question 1
What is the maximum number of rows and columns in an Excel spreadsheet?
3 rounds of interview, HR call, zoom call, onsite panel interview. Not too bad, ppl are cook. they asked technical questions, and also behavior questions. they also give you a chance to ask them questions about culture pay etc.
It was very swift and easy. There were three questions and all had to be done by recording yourself. There was also a coding question and SQP question. It was an hour long interview.
Lengthy but fair interview process. HR personnel, then hiring manager, then team members, and then a non-team person to give outside assessment. Good luck, as it seems tough out there right now.
