Had an interview on my college campus to start. They called back a few weeks later, set up a second round of interviews and site tours in Chicago. They paid for a rental vehicle and hotel room for a night. Had three interviews on this day with three different managers from throughout the company. After the second round, I received another call a couple weeks later for a third interview at a specific site that was interested. Again, they paid for a rental and reimbursed me for a hotel for the night.
