Met an alumni who was a manager in ERS at an accounting fair, gave him my resume and got a call from a recruiter days later. I had a phone interview for my first round since I couldn't make it to the office on the date of my first interview. After that I received an email inviting me to second round interviews and a special "Inside Deloitte" event. They paid to fly students in and put everyone up in a hotel (except I was already in NYC so it didn't matter). The night before interviews was a dinner attended by partners and other employees, they gave an awesome presentation and an office tour. Everyone was very friendly, they just wanted to make sure you were a good fir for the company.
