I inquired through email after my college passed on a message that a specific team was hiring shortly after I graduated. Applied officially online. Had a short phone interview and then 2 more 30 min phone interviews within a week. Mostly they just told me about what they did. Only really asked me to tell them about myself. I asked questions and tried to be 'insightful'. They implied I was hired but I had to take an iq type test. It took awhile to get through that and the background check (although they never actually said it was a background check... Just asked details about my prior work & education). That part is all outsourced to India and was very slow and took about a week. The iq test says you don't to prepare but I was frustrated to find I could barely remember the quadratic equation and other algebra topics you haven't used in years that were needed for the timed test. I think i did horrible, but they don't tell you how you did. Got an official offer letter from the Indian recruiting dept including bonus & relocation about a week later.
