Fairly relaxed, near informal interview style, asking questions about ability to fix equipment. The interviewers were middle management asking questions to attempt to determine personal attitude to work especially working non-sociable hours and also trying to determine ability to problem solve. There was no aptitude testing, instead a walking tour of the laboratory was undertaken and questions about various instrumentation was asked, where the interview was trying to understand if I was capable of working alone with these instuments, based on my previous experience.

Quick teams call, then an onsite interview. No proper structure. Ask some technical and behavioural questions. Two interviewers. No tests, just basic questions. Easy to answer. Declined the offer, as the salary seemed low.
