It's a placement agency so, yeah, don't fully trust those numbers.
Then again, you'd have to think that those numbers represent the sort of market that would use staffing agencies. So, if you want to come work for a financial titan, you can get more $$$ via direct negotiations / interviews. However, if you think you're coming here to work for an interactive media or B2B startup, then forget these numbers altogether. Those jobs pay everything from low market salaries to a cash/equity mix. We'll never get a clear picture of that market because, IRT insiders, it's in no one's best interest to talk about it.
