There is a certain art to interviewing for a job! Of course you need to have your ducks all in a row, so to speak, plus have a great resume plus a CV, perhaps.
You need to do your research on the job in question plus be prepared plus excited about it.
I have heard some people interviewing who evidently didn’t know a thing about the job they were trying to get. Be prepared, is the best advice I can offer. With that said there are a few things you simply can’t be ready for! The worst job interview I ever had was for an office job, plus I was ready for it but my a/c device was not. That morning when I got out of bed it felt sort of like the heating had been running all night, plus the whole locale was incredibly hot plus humid. I checked the thermostat plus the digital readout was totally blank, which indicated a major problem. I hoped it just meant the thermostat needed current batteries, but that was not actually the case. I didn’t have time to call for an A/C service tech at the time, because I needed to get prepared for the interview. By the time I finished dressing plus getting ready, I was dripping with sweat due to the complete lack of official cooling. I rode to the interview with the A/C device blasting in the automobile trying to cool myself down plus dry up some of the sweat. The interview was a total mess, because I looked terrible plus was off my game, but at least the office had excellent a/c in it.
