I applied through my college's Careers site, submitting only my resume I believe. I heard back within perhaps two-three weeks of applying. We set up a phone interview by e-mail. It started on time, and I spoke with a human resources representative. It was a general behavioral interview, with questions concerning my interest in management consulting, my knowledge of the company, and why I would be a good fit. It was good that I had researched the company in advance. The total interview lasted about half an hour. At the end, the interviewer warned me that future rounds would of course include case interviews, for which candidates would do well to prepare. About a week later I received a standard-worded e-mail denying my application.
