Technical
The interview process moved quickly. It wasn't tailored to my background, and the interviewer focused on their own area, which might not have been related to my background or the job description at all. There seemed to be a big disconnect between the interviewer and the recruiter. The process was fast-paced.

The interview process involved an AI interview. They asked questions about my CV projects, SQL, and a general introduction. I was also asked to justify my powerskills. Not giving long gaps made me a little tense, but overall the experience was okay. They asked me to explain the algorithms and models used and what is the use of the project in day-to-day life.
