Manager talked for 5 minutes and then turned interview to his subordinate whom mabnager had to call in and was late. The subordinate interviewer was low energy and not enthusiastic and had short accent and and I could barely understood his English. When the interviewer used acrynyms that I did not understood at first, The question was "How do you test Cat?" Then after I understood the terms and said I would connect this port to that port and etc, he changed the questions to "How do you find out what is wrong with the switch?" so i asked clarifying questions, he again changed the question to a different direction and caused me further conbfusion on what he wanted to know about my capabiolity or the topic. He concluded I did not know the topic, (Actually I did but not sure whcih aspect of the testing, SW, HW, or setting up, or protocol knowledge, or general teseting approach, he wabted to know.), he changed to "How do you test DNS?" which is the most simple and commonly used server. I answered "create an duplicate name or bad ip address....". He was not satisfied and ended the interview.
