I got the interview because a senior partner recommended me for it. Any partner in good standing can arrange for you to get past the resume screeners for an interview. First, there was a screening interview over the phone. This went very well, with normal interview questions about my background and the expectation that I would ask 2-3 questions about Deloitte. The point was to see if you can hold a conversation and act professionally. Then, there were two first round interviews, a behavioral and a case interview. I also did well on the behavioral interview. I prepared by getting the top interview question list from my CSO and making notecards with the interview question on the front and my desired response on the back. I came up with about 20-25 notecards. This strategy worked well. There was only one question that I didn't see coming and I was able to give a few really solid answers to the ones I had prepped. On the last question, the interviewer even said: "Wow. That was a fantastic answer." :) Where I ran into trouble was the case interview. My preparation was not well-suited to the interview. This was an interviewer-led case interview. After the initial prompt, there were 6 specific questions that the interviewer posed to me. Some were: "Given X, what factors would you consider in making your recommendations." But the ones that really killed me were the math questions. There were two of them. YOU HAVE TO PRACTICE MATH BEFORE THE CASE INTERVIEW. What is 20,000 times 60? What is 300 times 50? What is 50 million times 20? You have to be able to do these calculations quickly and confidently. Moreoever, you have to be able to do them consistently because one mistake can screw you over. Otherwise, before you know it you're stumbling and bumbling and you have lost the interview. Bottom Line: The case interview is EXACTLY like Deloitte says it is on their website, just with harder math.
