2 VERY Important DON’Ts!
While you may be very tempted, do NOT do either of these two things:
Don’t leave your current job without sufficient notice to your employer.
Don’t give notice to your current employer until you are holding a written job offer - that you have accepted, preferably in writing – in your hands.
Leaving your current employer too abruptly may come back to bite you hard in your next job search, when someone checks for a reference with that former employer (they won’t be happy with you).
And, turning in your notice in anticipation of a job offer can be a very big mistake when the job offer doesn’t happen because they ultimately chose someone else or the job was cancelled or put on hold. Don’t give your notice until you have received that official job offer. an interviewer who says he or she looks forward to working with you is NOT a job offer.
