I was approached by a very polite and professional recruiter on the LinkedIn, and his politeness made me apply for the position actually. The two interviewer did not have almost any precise answer to my questions. Besides, none of them was meant to be my line manager. They squandered a lot of my precious time. In the end, I did not even got a written feedback from them! I asked the recruiter and he said I would get a reply in written, however this never happened.
