I stuttered and sweat during my interview and they told me they had more interviews. Should I withdraw my application now? Like I said, I stuttered on a few questions and sweat in that tiny, cramped room which is a real disappointment because I feel like the two tasks I had to do as part of the interview, I did well and felt confident in, as well as most of my answers to the 8 questions, bar one or two They said they have “more interviews over the next two weeks” and will be in touch then and I’ve always been told interviewers telling you they have more interviews is never a good sign They also asked at the end whether I was interviewing elsewhere which I lied and said no to and asked about my notice period, too The only positive I can think of is that one of the panel was a former teammate in another team when I worked there last year and pretended like he didn’t know who I was so he could get on my panel Should I send them an email withdrawing? I’m sure sweating and stuttering isn’t a great look in an interview and could potentially have cost me the job!
