Easy and informal start of the interview helps "break the ice". Followed by a lab tour which was very professional and essential for a candidate. Then a detailed conversation about the post-holder duties and candidate experience. The interviewer came prepared - being familiar with the candidate's background, research interests and papers.

Got an interview invitation a week after the job ad deadline. The interview was scheduled for the next day after I received the invitation because it was a short-term temporary role, and they needed to use the funding by a certain deadline. The interview went well: there were two interviewers, and they asked both technical and communication-focused questions. Afterwards, I received an email asking about my visa status and whether I could provide an additional referee. I then received an official offer a week after the interview.
