It’s actually funny and shows how nervous candidates are while facing the interview.

I was interviewing a female fresher few years back and she was all sweat. The anxiety was so high on her that when I asked her a question, she was all quiet. I said, “Go ahead” and she got up to leave my cabin. I was all surprised and asked her what happened, she mentioned that you only asked me to go ahead! She mistaken my go ahead to answer the question as leave the cabin. Can’t explain how hilarious the overall experience was.
