Super unprofessional. The recruiter kinda ghosted me after the initial contact but eventually got scheduled for an screening interview. The interviewer was rude, unknowledgeable, leading with a know-it-all attitude and suggesting bad patterns to the point that I started questioning to myself if the purpose of the interview was to see how I would react to a situation like that rather than a technical, screening, interview. Kept my cool, solved the problem, but I didn't pass to the next round.
