I applied online, and the process took three weeks.

After applying initially, I was asked to take a GRE-like test that had (I think) seven sections lasting thirty minutes each. After that, I was asked to take two more tests that tested programming skills and one test that asked questions about myself and why I'm interested in working at the firm. There was also a psychometric test. I had an interview with the recruiter after that where she mostly asked me questions about myself and my experiences, but I didn't make it past that round. Overall, it was a good experience, and the recruiter was friendly and responsive, and things happened fairly quickly. The firm even gave feedback on why I was rejected, which I appreciated.

The discussion was just stuff about projects, interests, and past experiences.
