Was already working at Dell as a contractor; submitted resume in response to internal job posting. A week or so later, I was contacted by HR consultant who held the screening interview and set up following interviews. A few weeks after that, I had a phone interview with the hiring manager who lives in Europe. Followed with phone interviews with employees who would be my teammates. There was a long delay (2 months) with no news while the position was officially approved - explained by the HR consultant who did not contact me but finally responded to my several calls and emails asking about the status. Shortly after that, I got an offer from the HR consultant.

Phone screening followed by in-person interviews. 4-5 interviews with folks from same or related teams. Questions are usually pretty standard - mix of questions around your resume and situational "tell me about" questions to test your background as well as your skills.
