Had a phone interview in October. Was asked to fly to headquarters in December for three consecutive 1:1 interviews, once case. Everyone was very nice and helpful throughout the process. The case was not bad, simple P&L, earnings projection, barriers to entry, etc... Other two interviews consisted of typical questions; tell me about yourself, why IBM, where do you see the company going, name a time you had to learn on the fly, etc... Interviewed with roughly 30 others people.
