I had a short phone interview with HR as the first step. Once I passed that they set up an interview in their ann arbor, mi office. Interview was about 1 hour long. There were 2 interviewers that asked me personality and work experience questions. One of the interviewers stepped out and the other asked me technical questions in mySQL and perl. Gave me an interview question that was to design a sql database for a scenario and create methods in perl to connect to the database and return specific query data. Databases were a little complex, similar to higher level text book scenarios. Interview overall went pretty well. I wrote thank you emails the next day. I didn't hear back right away and emailed a few days later. I got a response back from one of the interviewers stating that they choose another candidate. The HR ended up responding back a few weeks later and wanted to schedule another interview because the position opened again. I already had a job at that point so I didn't follow up again.
