When scheduling the interview I was provided an address, but they neglected to mention that it wasn't in the main building. I called my contact from the lobby of the hospital and he told me to drive to another building in the back.
Pretty basic interview. Very few technical questions and everyone was very friendly. At the end of the interview I was told that they had one more person to interview and they would let me know in about a week. I called the hiring manager 10 days later because I hadn't heard back. He sounded very irritated and told me they were still interviewing. I never heard anything after that and took another offer. I was also irritated that the job posting said Manassas, but in the interview he said the position would be in Haymarket.
