A slowdown in tech hiring among the long tail — smaller firms outside the major markets — coupled with a falloff in financial services hiring has prompted Dice Holdings to reduce its revenue and earnings outlook for the rest of this year.

Some staffing companies have cut back their advertising, presumably because their clients are saying they anticipate needing fewer temp workers in the coming months. However, the biggest impact, said company officials speaking with financial analysts this morning, is coming from small firms and from firms outside the tech industry.

“Tech is still tight,” said Dice Chairman, President and CEO Scot Melland in response to an analyst’s question. “But it tends to be tight in the tech centers. When you get outside of the tech industry and the tech centers, it’s a different story.”
