I applied through other source. The process took 6 weeks. I interviewed at IBM (Cambridge, MA) in Jan 2013
Interview
Hiring process was initially a little difficult as it looked like they weren't initially interested, but upon obtaining an offer from a competitor, they perked up and quickly moved through hiring.
I applied through college or university. The process took 4 weeks. I interviewed at IBM (Armonk, NY) in Sep 2008
Interview
Without much fuss but maybe a bit slower than smaller, more agile companies. Very heavy on in-person interviews to test fit and overall candidate performance. The screening process for my particular position started at the university with a phone interview and closed with a intense 4 interviews in one day session a couple of weeks later. Emphasis is on fit (passion/enthusiasm for the industry and company) and business cases that require some creative thinking and basic understanding of the IBM business model.
Interview questions [1]
Question 1
Heavy on business cases that are somewhat IBM specific. Reading up on the company's strategy helps and is expected.
