They came to a campus event and set up on-site interviews. After successfully completing an on-campus interview, I was accepted into the blitz. They are really wonderful in the regard that they genuinely take care of their recruits. They will either fly you in or let you drive and compensate you for your milage. The interview "blitz" lasts 2 days. You arrive in the afternoon, are provided with a catered lunch, and afterwards there are a series of information sessions, followed by an evening networking event. Some of the people with whom you are networking will be interviewing you the following day. I encourage you to speak with as many people as possible. I also encourage you to make friends with your cohort- these are the people with whom you will be cooperating the next day during the group activity. The following day, there are interviews and a group activity.
For the interviews: Any connections you may have made during the initial networking activities will come in handy here. The interviews experienced by my cohort were two-person panel interviews lasting 45 minutes in length each. They ranged in difficulty depending upon with whom you were interviewing. The questions were largely behavioral based.
For the Group activity: They are watching you to see how you work with others in a group setting. Do not over-act. Do not try to take over. Do not try to "look like a leader." The goal is to see how well you listen to each other. Compromise is rewarded, and influence does not appear to matter- though they did not explicitly tell us that it did not. I wish you great luck in this endeavor.
Finally, they show you the city. Memphis seems like a great place, although we didn't really get to see much.
