As someone who's conducted interviews for GIS postitions, I've taken a different tact

than most. A person's resume should have already given the interviewer a solid idea of

the interviewee's training/abilities, so I don't really go there (beyond the basics). We

use a probationary period to weed out the liars/exagerrators (we've been lucky so far).

Basically, if someone is GIS-certified, they'll be able to answer any of Thrillhouse's

questions.

IMHO, in today's job world, personality is at least as important as training. I can teach a

competent person the basics of Arcview/MapInfo in a afternoon -- especially what's

required for an entry-level position.

On the other hand, dealing with a well-trained ass who makes everyone in the office

tense just isn't worth it.

Of greater importance to me is work history (or lack thereof or huge temporal gaps)

and general attitude (be keen, but not too keen...). I also like it when the interviewee

has taken the time to research my company. A small portfolio of past work is never a

bad idea either.

Talk about long-term goals (to advance within Company X, of course!) when given the

chance. Have a couple questions ready to ask the interviewer -- that's the one that

usually messes people up.

My standard set of questions always includes "why should I hire you?" and "tell me

something interesting about yourself that isn't on your resume"
