IBM Software Developer interview questions

I took an online interview with IBM. The whole thing was a HiredVue facilitated by Watson. I enjoyed the interview and did well. I did not hear back from them for 4 weeks. When I did, the email said that I was not being considered because of my need for sponsorship (even though I am a US citizen). They followed up later apologizing for the previous email and asking me to share my availability to interview within the next two weeks. By this point, I had already accepted another offer.

Process Heavy. IBM looks very closely at your history from the past 7 years. This is very time consuming. Pointless aptitude testing has nothing to do with the job. 3 interviews with managers - 1 tech - 2 HR
