8x8 Backend Java Developer interview questions

I had applied to 8x8 through the career fair in my university and I got a call from a recruiter almost after 2 months. There was no telephonic interview and I was called directly for an onsite interview. I was asked to bring a laptop and it consisted of an hour long coding quiz followed by an interview with one of the member from the engineering team. The questions for coding quiz consisted of implementing an LRU Cache, Producer Consumer problem and one more question. I was not able to finish all of them in the given time. After an hour long code implementation, I was interviewed with one of the engineer. He asked me questions on the code that I had written and why I had written in a certain way. He asked me all basic java questions - threading, synchronization etc. His english was not very clear. So, at times it was hard to grasp what he was asking. I had to ask him to repeat the questions couple of times. But overall the interview was ok.
