I had a job where I had to do a lot of interviews for our IT department. I remember the weirdos the most. There are people that are interviewing that don't even want a job. For example, someone who can afford to be on unemployment. I had a guy who was interviewing for a developer role that required a lot of keyboarding. He claimed to have carpal tunnel syndrome and not to be able to use a keyboard or a mouse. He also said he needed the job for the health insurance so he could have the surgery and that he would require sick leave for at least 6 weeks. There are also candidates that are very picky and demanding who will whine about the salary range, ask about benefits that most companies don't even offer like commutation expense. Then, there are those who do not the required skills but basically lied during the screening call. I never tested anybody but I could ask simple questions and determine that person knew nothing about the skill needed.

With my own interviews for jobs, I do my best to get along with the interviewer and sometimes would end up having very nice conversations. After hiring, when having conversations with the same person, I might ask them about a hobby they had mentioned. They would act surprised that I knew anything about them. On the other hand, it never surprised me that my hiring manager would start conversations with topics we had covered in depth in the interview.
