I saw some positions online, and I applied to quite a few. I called some local HR managers at the sites, and no one helped or was really willing to help, kept saying, "corporate does that, we can't help." Which isn't true, because one HR manager took the time to help and forwarded my resume to a contact she had at corporate. That was on a Tuesday, I got a call from the HR recruiter from corporate on Wednesday and setup some phone interviews. The first one was more of a background, "tell me about yourself" type of questions, pretty simple. On Friday, he called again and discussed more situation based questions "tell me a time when you..." The recruiter liked me and asked if I wanted to go to the site and conduct some interviews, I said, "yes!" They flew me out there, had an initial tour of the facility. I would ask questions and be engaged in the process, because I think it's a part of the interview process, to be honest. Then we had an HR brief explaining a little more about the position. Then I conducted three 2:1 interviews, and those were more "tell me when...", "how did you deal with a poor performer...", etc. Very scripted interview, they have a sheet they read for each question. I would definitely understand the STAR method, situation, task, action, and result. That's the format they are looking for during the interview. Forty or so minutes later, I got a call from corporate to setup a 'final' phone interview at a later date that was a "conversation type of process." It took 15 minutes, and the person I talked with was responsible for an area and wanted to get to know candiates. About 30 minutes later, the recruiter I talked with at the beginning called me, and asked me how I thought the process took and if I liked the people at the DC, and then he gave me an offer.
The further you are in the process the better you should feel about getting hired.
Hope this helps.
