I met a research staff member at a conference and revealed my interests on the company. Then I had a phone interview with the staff to confirm my qualification. Then I was invited as a seminar speaker. I talked to 4 postdocs/junior staffs in the morning, gave a talk at noon, and talked to 4 senior staffs/managers in the afternoon. It went well. Most of them are interested in my current research. A potential manager asked me a hypothetical question about how to deal with a specific technical problem. I had a positive experience at IBM. The job opening came up after 3 months. They are interested in my so they contacted my reference about my qualifications on that position. My reference said the position might not fit my background therefore I did not get the offer.
