Broadcom Engineer interview questions

I was contacted by the director of the team. For which I responded. Then there was no follow up for a month. When I texted back, I got a call and a telephonic interview was scheduled to be taken by a engineer in his team for a vague time the same day. I got a call after 2 days. And a face to face interview was scheduled for the next day. Right before I was leaving for the interview I got the call that the interview will be telephonic later the same day, which happened well. After 2 days I got a call from the engineering manager for a face to face interview again. When I reached, again a discussion with the engineer happened which was good. Then comes in this manager who was totally absurd and RUDE from the first second. Little dignity he didn't show for the position he had. Absolutely disrespectful.
