First stage with HR manager, general questions about my experience and the role. Second stage with ML Lead and two other engineers. Lots of hypothetical questions about applying ML to their use-case including ball tracking, data annotation pipelines, CNNs vs Transformers. Very friendly team, felt relaxed and easy to talk. Hiring manager thought I wouldn't be experienced enough for the role, made it to next stage anyway which I think went well, but received an email in the end saying I didn't have sufficient experience. Email included good feedback, overall experience was pleasant.
