Tintri interview questions

One telephone interview. 5 technical interviews on-site. Questions were very straightforward and simple on algorithms, os concepts. Most of the interviewers were good apart from two guys in which one needed to improve his interviewing skills and the other had no reaction to whatever I was saying to him. The first guy asked me how locking is implemented in distributed file system. I am from replication background, and I was a bit surprised that he choose to ask me this question instead of testing me on file system locking fundamentals. Also instead of driving me to the right path during the course of interview, he was just saying "it won't work" for everything I say. Sometimes, I felt this was more of a competition between me and him than a interview. Also his question was very abstract and I had to ask him a lot of questions to understand what he was trying to say. Clearly, I felt he needed to improve his interviewing skills and also communication skills. The other interviewer had no-reaction on this face to whatever I said. Not sure if he was interested in interviewing me. I did solve the problem in the end but after trying a lot to get some reaction from him. I got demotivated during the course of interview with this experience. Overall, the experience was mixed but I felt some interviewers needed to improve their interviewing skills.
