I've been blessed in that each time I've needed a job change - I gone after something a little beyond what i thought I was qualified for ... and .. I landed every opp. Way back in the early 90's I read numerous job interview books, etc... They were helpful and I carry some of that knowledge with me to advance my career when needed.
Some of the bare bone basics :
- dress to impress and be prompt
- have examples of success and failure that are good stories... and of course how you overcame the failure.
- have examples of your overall strengths and weaknesses as they relate to the job (a cheat is to say something like you find that you can sometimes be TOO detail oriented and you are working on being more efficient rather than meticulous.)
- have examples of people in your life that inspire you and why they do.
- go into EVERY interview with the attitude that you have nothing to lose and... really.. you are interviewing them too. nothing worse than accepting a job and hating your life because of it.
- be conversational when appropriate - friendly is good - stoic is scary.
I am sure there are a bazillion other things the "pros" will tell you to look out for... but those basics are my priorities when I interview and I've had great success in heavy heavy competition.
