I am not from a school they typically recruit from for internships. I had to apply online, and luckily knew a few people within the firm. I worked diligently to make myself known, through phone conversations with a recruiter, emailing a partner that I had a mutual relationship with (I don't recommend this unless you are certain of the relationship and how they may react), and checking in fairly often. Had an initial screening with recruiting, a phone interview with HR, and then a full day interview in the office with a partner and two managers (all separate 1 on 1 interviews). Had my offer the same day, though that is not always the case/common. Often times you hear back within a week or two with a verbal offer.
