I emailed head of lab, asked to volunteer. He met with me and discussed what I wanted to do in the future, then told me they didn't really do what I was interested in at the lab. Then after three months of working there they hired me

The first part of the interview was fairly easy, pretty basic description of the job and was asked about prior experience as it pertained to this job. The second part of the interview was done completely in Spanish (as they wanted someone who was bilingual) asking about experience with specific tasks.
