Best Way to Decline a Job Offer?

Dear Experts, I got offered a job last week and something doesn't feel right about it. The people that work there are all very quiet and look almost scared. The boss seems serious, but didn't act mean. However, when I asked why the position was open, he did comment the last person didn't have a 'strong enough personality' for the job. That worries me. I accepted the job and said I'd start this week, but now I don't want to go! How should I decline the job? Here is how our T.A.P. experts answered this question:Q#336 Polite "thanks, but circumstances have changed" suffices. Following UR gut wise. Good for U 4 listenting. (@dawnbugni) Q#336@heatherhuhman's article is spot on:"Write brief, thoughtful (polite) note saying ur declining opportunity, etc." (@ValueIntoWords) Q#336 If u have no other prospects, keep the commitment and give the job a 30 -60 day probation & then decide. (@TaiGoodwin) Q#336 If ur gut says "NO" say ur circumstances changed, no longer able 2 accept job, very disappointed/sorry. (@juliaerickson) Q#336 I would go anyway. If you planned to turn down the offer, you have nothing to lose by leaving after 2 weeks. (@gradversity) Our Twitter Advice Project (T.A.P.) is no longer an active campaign.
