TechRepublic: Six ways to shoot yourself in the foot during an IT job interview (PDF, registration required)

Pretty standard things, like "talking tech to non-technies," "allowing electronic interruptions," or "neglecting to send a follow-up thank you letter."

These are all obvious. I'd like to add a few others to the list of potential tech-interview screw-ups:

• Smell bad -- You should not arrive at the interview smelling of perspiration, curry, fried food, excessive perfume or cologne, or diesel fuel. If first impressions count, make sure your odor isn't an issue.
• The Cold Fish -- Learn how to shake hands, people.
• Don't speak -- We aren't hiring you for your pretty face, darling. You must come to the interview prepared to speak. If you mumble your way through the first few questions, you'll quickly shuffle back through the front door.
• Don't stop speaking -- If this isn't your first interview, you may have noticed that the general format is question / answer, and so on. The question part is where you don't talk.
• Lie -- if you stack your resume with things you haven't done, or haven't done well, it will be obvious. People who do interviews for technical positions often have chips on their shoulders: if they see their pet technology on your resume, they will grill you on its most minute details. They may grill you even if don't list the technology on your resume. It is a lot like a thesis defense in that respect. If you are lying, it will be obvious.
• Do the Dale Carnegie -- You are interviewing for a technical position. Unless you are interviewing with morons, your sparking personality and powers of persuasion will only get you so far. Be prepared to answer some of the questions correctly.

The way around this, of course, is to know someone. If you are the CIO's buddy, you can be the most moronic, unqualified, fraud in the industry, you'll probably still get that management position.
