Process
For the very first question, I misheard the phrase 'hash table' as 'test table', so I told the interviewer that I had never heard of a 'test table'. Of course, the interviewer was very surprised when I told him that I had never heard of a 'hash table'. Fortunately, the misunderstanding was cleared up soon, and the rest of the interview went well.
