Interviewer called in 15 minutes late, but ended interview on time and resulting in Q&A being cut short. Halfway through the interview, the interviewer's voice got really muffled (I suspect she is too close to the mic) and I attempted to inform her about it but she repeated the question anyway). Try asking someone to repeat a question 3 times and he/she will definitely feel a certain level of frustration. The questions were skewed towards interviewer's expertise at work, which resulted in my interview turning out like a quiz instead of an actual interview. At the end of the interview, I felt demoralised and subtly graded down with the curt 'ok thanks' response.
