Cloudera interview questions

I had a phone-screen from Cloudera last Thursday. The call went well except I really had a hard time understanding the interviewer due to his thick accent. His questions were quite open-ended and so we had to go back and forth multiple times before we decided on what he really intended on asking in the first place. But I was able to answer most of his questions properly and he seemed quite impressed with the quality of correct answers. One of the answers however he wasn't sure about, but he didn't bother clarifying or giving me the answer that he was looking for. I asked him for clarification but he kind of ignored my request and moved on with his questions. At times he seemed quite rude because I think he was getting frustrated trying to explain things concisely, but I didn't give it much significance as I attributed it to the communication problem we were having. I kept up a good attitude and carried on. I can't really say if the screening went well since I was left in a lot of doubt regarding the communication barrier.

Wait for almost two months to get a phone interview, the interviewer was polite and patient, but I knew I performed very bad.
