It's been a while back, but from what I remember it was a relaxed casual interview. None of the competency questions, which I appreciated a lot. Wanted to know a lot about what I think of them and how do I find them, and how do I imagine a day of work as a lab technician. After a successful interview, they invited me for a trial day, which was an almost full 8-4 (unpaid). After a trial, another casual interview, where they wanted to hear about how did I like the work there. If it's how I imagined it would be. If there's anything I wanted to know... I thought it was going great, but more than a week later they phoned me and told me they thought this position wouldn't be enough challenging for me, so they chose a candidate who they thought would benefit more from it. I guess you can't say that you're familiar with all the work they make you do on a trial day. I only thought that would be positive asset.
