I applied through an employee referral. The process took 2 weeks. I interviewed at PIMCO (New York, NY) in Sept 2012
Interview
Initial HR phone screen with Recruiter, 1-2 calls with the business, on-site interviews depending on interviewers' availability may be 1-3 rounds of on-site meetings. If non-local candidate, Skype interviews are great alternative. Certain positions require assessment/writing samples/test, case-study.
