Be honest, but do not badmouth any employer you've worked for.
If you do, the interviewer may wonder if you'll do the same
about his company.
Describe the position, rather than just naming it. Offer a
reason why the position was so satisfying.
Some interviewers want to know about childhood jobs, while
others are more concerned with your first "real" job after high
school or college, so ask for clarification, or briefly
mention early jobs before you talk about the first "real" one.
Be specific. The interviewer is wondering what process you
go through to make a decision.
To answer this question, you'll either have to think fast or
prepare an answer in advance. Think about your entire career
and be able to fully discuss three of your successes.
Select the one that applies most to this company when answering
during the interview.
Show your creativity, but don't sound like a "loose cannon."
Even if you had no authority to make purchasing decisions,
you still could have helped the company save money.
Try to sound as though you have good ideas, but you do not
presume to know the company better than the owner. You want
to sound confident, not cocky.
Here's your opportunity to shine. Talk about your
creativity and innovation,in addition to your attention
to details.
