I've initially applied online on the website, but apparently my application was "lost" by the office I ranked first in the process, and then tought I was rejected from all office. Two months later I discovered this fact, and applied directly to the office by email. In 3 days I was contacted and scheduled for the PST in a 2/3 months (just missed one). But in the end this was good news because I trained a lot, using both online and paper resources: caseinterviews.com; Case in point; How to get into top consulting firms. I cumulated 50 practice cases, 100+ hours of preparation, and GRE/GMAT training for the PST. The test was very hard, time is tight and i had to answer a fair number of questions with educated guesses. But I guess the threeshold to pass the test is not so high. Then I was called back for a motivational interview (eg tell me about a moment in which you demonstrated leadership) with a case, and then a little space for my questions to the interviewer, which are no less important! Then the final round, with the same motivational + case format repeated 3 times in a day. Then I received the offer. The only suggestion: be prepared, and think about every single word or assumption before it leaves your mouth! It should be inserted in a structure that you should have already presented to the interviewer. And be relaxed and relatively friendly: they also want to check if they'd like to work with you till midnight without pick up a fight or get bored, or if you can meet a client and get along with him well without embarassing the firm.
