Calamatta Cuschieri interview questions

A HR representative from this company approached me via Linkedin. I agreed to have a conversation with them. Big error. They were impolite, moreover the hiring manager chewed gum throughout the interview. Never had a response from them, not even an automated email.

Met through Teams primarily. 3 interview stages, first HR, 2nd HR and manager, final interview with HR, manager and head of department. Average, lengthy, pro longed. Took over a month to get an answer
