I applied online. The process took 1 week. I interviewed at Citi in Dec 2009
Interview
First interview was a phone interview. It was very positive. Recruiter covered experience on my resume. Second interview was in person. Nothing outstanding. The interviewer was hiring manager. He was laid back, very vague when describing the job and answering questions about the job.

Campus Selection Process, pretty smooth with multiple rounds of personal interview. Usual questions. No case study etc. Interviewers were patient, heard thoroughly & asked counter questions. The result was shared immediately after.
