there is (was) a book called “Sweaty Palms - the Art of Being Interviewd” - if it’s still in print, might be worth looking at. check the libraries.
don’t pad the resume - you never know when you might encounter an interviewer who can call you on it. for example, i’ve interviewed applicants who put down that they’re fluently bilingual, French/English. I happen to be bilingual, so I always ask a couple of questions in French. if they can’t reply in French, their chances of getting the job go down drastically.
“Be Prepared.” One of the best interviewees I’ve encountered came in with a prepared list of questions in a folder - salary range, duties, benefits, any travel requirements, chances of advancement, etc. as we went through the interview, he ticked off the points, and then at the end asked about the things we hadn’t covered already. He was very much in control of the interview - almost as if he was interviewing us for his purposes. If done properly, leaves a very good impression of the interviewee as a self-starting, thougtful person.
watch your body language. we had one guy lean back in his chair, with one arm dangling over the arm. conveyed the impression that he didn’t really care much about getting the job. well, if he didn’t care, why should we?
know your stuff. we’ve scratched people off the list who asked stupid questions that showed complete ignorance of key areas. if you don’t know the answer to a technical question, say so - but then add immediately how you would go about finding the answer to the question.
asking the interviewers why they work there and what they like about the company is a very good question - people like to talk about themselves. plus, you might get some feedback, intentional or not, that could signal that you might not really like working there.
