There is a particular art to interviewing for a job position… Of course you need to have your ducks all in a row, so to speak, plus have a stellar resume plus a CV as well… You need to do your research on the work in question plus be completely enthusiastic about it.
I have heard some people interviewing who clearly don’t know a thing about the work they are trying to get.
You must be prepared, that is the best advice I can give. With that being said there are a number of things you simply can’t prepare for. The worst work interview I ever experienced was for an office job position. Honestly I was ready for it however my air conditioner appliance was not. That morning when I got out of bed it felt basically like the heating had been working all night, plus the whole location was tepid plus humid. I checked the temperature control component plus the digital readout was totally blank, which indicated a serious problem. I hoped it just meant the control component needed brand new batteries, however that was not the case. I didn’t have time to call for an AC appliance repair tech at that particular moment because I needed to get ready for the interview. By the time I finished dressing plus getting ready, I was easily dripping with sweat due to the lack of usual cooling. I rode to the interview with the AC appliance blasting in the car trying to cool myself down plus dry up some of the sweat. The interview was a complete mess, because I looked entirely awful plus was off my game, however at least the office had superb a/c in it.
