First off, it's important to note that this company is more interested in how well an employee will fit in with their culture than any others I've come across. Whether or not they like you will play a large roll in if your interview/hiring process is like mine was, or if you'll see something different. They mention their company values as part of every job posting, and if you don't feel like you possess those values, or you don't look like you possess those values, don't even bother sending in a resume. How desperate they are to fill the position may also play a roll.
First, I'll describe my personal experiences while in the hiring process, and then I'll share some of my observations from watching other people interview and get hired.
I saw the position opening online and sent my resume and cover letter to the email provided. I received a call and an invitation to interview the next morning. I arrived early, and was soon greeted by my eventual manager. I found out that there would be three people interviewing me; the CFO and a programmer were included besides the IT manager. The personal will vary depending on the position, but as far as I'm aware the CFO sits in on all interviews.
The questions were more centered around my resume than actual knowledge. The people were extremely nice, so it was definitely one of the lower-stress interviews I've been a part of. Afterwards they asked me if I would mind showing them my computer skills. I said yes and they led me to the waiting room, and then the CFO and manager returned to have a private conversation. I could tell I had impressed them with my educational background, if not my actual job experience, and figured as long as I didn't completely gaff up the "test" I'd probably have the job.
After the manager returned he took me back to the work areas. The company employees an open floor plan, something that at first threw me for a loop, but later turned into something I appreciated (although now I think it's a little too distracting for the IT section). The manager showed me a problem they'd been having with their system and asked me to write down the steps I'd take to fix it. I honestly had no idea what to write, or even what to do, so instead I just started verbally explaining the steps I'd take to discover what the problem was. It probably wasn't the best answer, but I must have made myself sound just smart enough because the manager then offered me the job on the spot. I had several other job interviews lined up for later in the day, and although I could make more money elsewhere, I was impressed with the culture and excited to do something in at least the same field as I was studying. I accepted immediately, and started work on Monday.
After that, it was just filling out the basic paperwork and having the basic meetings before I was thrown to the sharks. In the IT department, none of the jobs have any training, you are simply expected to learn by doing. Other departments are different, but if you're planning on working in the IT department, don't fake intelligence that you don't have or your fallacy will quickly come to light.
