I used an agency, and I think almost everyone has to, to get the interview because they have a 90 days probation rule where they would prefer to pay you via the agency. I got requested to come in for the interview out of state, there is no reimbursement for travel expenses like with other interviews I've been to. I met the group manager and the senior hr manager. He/She asked me all the questions about my resume while the senior hr manager only informed about the salary and position descriptions. It lasted all of 30 minutes, after I was kept waiting in the lobby for maybe 15 minutes.
