I interviewed with several groups at Salesforce, each of which was initiated via employee referrals. Both groups followed the same basic interview process: 1) A call from a Salesforce recruiter who provides information about the position and gauges your level of interest. 2) A short screening call with the hiring manager where you can more detailed information about the position and also see to if you would be a good fit for the position and the team. 3) Typically an online three-hour coding exercise -- plan on using the full three hours. 4) Interview with the team, anywhere from 5 to 8 team members. 5) Assuming the team wants to move ahead with the hiring process, the final step is typically to have a 30-minute phone call with a VP. A Salesforce recruiter manages the entire process. I was extremely impressed with the Salesforce recruiters I was working with, they were always responsive to questions I had and kept the interview process moving along in a timely manner.
