Interview was quit long (around 3 hours) which might sound dreadful, but it wasn't. They chatted with me for a few minutes about hours, pay and benefits. Then they showed me the lab and let me talk alone with an employee so I could ask him some questions. Lastly, they took me to lunch with the HR guy, the supervisor and another employee. We just chatted and had the opportunity to ask and answer a few questions. It was really nice actually.
