Marvell Technology Senior Design Engineer interview questions

I had three round technical interviews. The questions are reasonable not too bad. But I did not get the offer.

Very unpleasant experience. First I got a phone call from the hiring manager at around 9PM. We discussed my resume. Several days later, I was brought on site, face to face with the hiring manager and an senior guy in the group. We talked about my experience first. He asked many strange questions about my past. Later on, he asked me some technical questions. For 1 questions, I couldn't answer and ask him for feedback. He gave me a wrong solution. I was very disappointed at his manner and knowledge. I wouldn't recommend this company to anybody.
