Prollenium Medical Technologies interview questions

Applied for job role on LinkedIn and got a screening call from their HR within 3-4 days. It was followed up by a second call with HR to discuss role and experience in detail. Third round was with Hiring manager and one other person from the team. This round was in-person and the questions asked were quite vague to be honest. The manager conducting the interview seemed very difficult to talk to and gave judgemental looks throughout the interview. The HR then ghosted even after following up with him several times.
