The last interviewer was via video conference. In the beginning, I could hear his voice small and remotely, although we tried everything. Several times I had to ask him to repeat, and that limited my interaction with him. Also, although he could hear me, I was unconsciously trying hard all the way to speak loud due to empathy. In the middle of an interview question, his voice was completely gone. 5 minutes later the IT lady came in again, tried everything, it still didn't work. She then went to prepare another room. 5 minutes later, I had to move to another room, rewrite what I just wrote on the whiteboard (because I needed to prioritize the list of features the next step). This last interview was quite disturbing and definitely impacted my performance. I requested the hiring committee to take this into account (say, discount the last interview result, or quickly reschedule 1 interview since I live locally), and got a No.
