Initial video interview as is standard with these positions then onto a second stage, in-person interview. Between applying, the initial interview and the in-person interview, this part of the process was relatively quick.
The second stage interview was gruelling, as the format was highly unusual, with me stationed in a single room while person after person (5 in total) came in, each with a copy of my CV. For each of these micro interviews we chatted about my CV, previous experience, current work, hobbies and did some technical questions/assessments. One very unusual thing about the coding questions was that it was pen/paper, rather than in an IDE (???). These questions were fairly interesting, but very exhausting by the third iteration, with still 2 more to go.
All interviewers were very personable, bar one. Another reviewer mentioned that one interviewer did not greet the interviewee or say hi, I think I know which one that would have been and I found him extremely rude. He remarked that my work experience was strange, commented that my choice of University was "weird" (direct quote), made faces during our conversation and was generally very sarcastic with his remarks- highly unprofessional for an interview.
An overall negative experience. I would advise others to prioritise interviewing elsewhere first, but with how the market for graduates in this field is, we will all just take what we can, of course.
