The smelly food eater
This person will be sitting beside you having curry for breakfast on the morning you've got a hangover.

Mr Disagreeable
Any meeting with this guy quickly turns into an argument. He lives to contradict others. He never makes any suggestions of his own.

The parasite
Another one of those pesky technical people who've never bothered to learn technical skills. This person drifts from project to project attaching themselves to more competent colleagues or "mentors" as they sometimes call them. They make sure the mentor is accountable for the project, so it will be guaranteed to be done well. Then they send the odd email, produce a couple of documents, and wait for the credit to roll in. If the project goes wrong, they make sure that it's known they were only there to learn.

The attractive girl with a short skirt
At first this person appears as if she's going to be a great colleague. It won't be long until she has your entire team at each other's throats though.

The code thief
Now I don't mind when other people use my code in their applications, actually I find it flattering. What I do mind is when they just rip it out without telling anyone else and then pass it off as their own work. I also don't like it when components or applications of mine are given cosmetic changes that make it look as if they've been reworked rather than just stolen.

The nitpicker
Prepare to have anything you ever do gone over with a fine tooth comb and mistakes pointed out to your boss. This guy won't be happy until you're a quivering puddle of humiliation.

The music imposer
The company doesn't provide you with sound cards or speakers? Don't worry, this guy bought his own from home. We all know that nothing helps more than blaring New Guinean rap music when you're struggling with a difficult technical problem.

The seventy-hour week guy
He'll be in when you arrive and still working when you go home. He's often in on the weekend. It's only a matter of time before management starts encouraging you to follow his example.

The mobile phone left on the desk person
Always in meetings or out to lunch, his mobile phone rings constantly at full volume. His choice of music? The Ride of the Valkyrie, of course.
