TRAPS:  Skillfull interviewers sometimes make it almost irresistible to open up and air a little dirty laundry from your previous position.  DON’T

BEST ANSWER:  Remember the rule:  Never be negative.  Stress only the good points, no matter how charmingly you’re invited to be critical.

Your interviewer doesn’t care a whit about your previous boss.  He wants to find out how loyal and positive you are, and whether you’ll criticize him behind his back if pressed to do so by someone in this own company.  This question is your opportunity to demonstrate your loyalty to those you work with.
