A few days later I was invited to in-person interviews. Deloitte flew me out on a Thursday night, and back Friday afternoon. The format was 1 case and 2 behavioral. To prep, I walked through Deloitte's case prep online, made sure I had solid experiences to share for about 5 different types of questions, and had a good "story" to tell about why Deloitte and why I wanted to switch. Case: Very straightforward. I was given the paper with the case on it. Focus was on an ERP implementation. I took my time to organize an initial response and explained how I setup/grouped the info (Strategy, opportunities, challenges). The interviewer walked me through the case, asking questions and followup questions. Key advice is to link everything back to the strategy, bring in ideas not in the case, and be able to come up with how "your" services will add value (+profit or -cost) to the company. Behavioral: 2 separate interviews. Very similar. Be able to have solid examples that show a variety of experiences. Be personable, that is what consulting is about. Be able to show results and value from your past experiences. Afterwards I followed up with emails. Heard back the following Tuesday via a phone call. Took about 2 weeks to work out the offer before I accepted. Everyone I met was incredibly friendly and professional. Very impressed overall.
