* Company slightly beats sales forecasts in Q2

* Says hiring "resilient" in July

* Much of revenue increase due to higher wages

* CEO confident of taking market share

ZURICH, Aug 3 (Reuters) - Adecco Group is seeing more caution among companies on hiring decisions and by candidates putting themselves forward for new jobs, the staffing company said on Thursday, as it reported its second-quarter earnings.

The Swiss group became the latest staffing provider to flag "challenging" conditions weighing on sentiment following weakening economic data.

Rivals Randstad and ManpowerGroup have both highlighted tougher market conditions in recent weeks, as have London-listed Hays, Robert Walters and PageGroup.

"It's true, the overall macro economic situation is not the best," Adecco CEO Denis Machuel told Reuters. "We see some indications of slowing down.

"We are seeing companies being more cautious when it comes to permanent hiring, candidates are also being more cautious. When it's cold outside, you tend to stay home."

For the April to June period, Adecco reported net income falling 19% to 62 million euros ($67.7 million), missing forecasts for 80 million euros.

In the same period sales rose 1% to 5.99 billion euros, slightly ahead of forecasts for 5.98 billion euros in a company-gathered consensus of forecasts.

Adjusted for trading days, currencies and acquisitions, revenue increased by 4%, better than the 2.3% increase expected by analysts.

Most of the increase came from higher wages, Chief Financial Officer Coram Williams said, with hiring levels "very modestly down".

Adecco, whose results are seen as a proxy for the health of the broader economy, said hiring in July - the first month of its third quarter - had been "resilient".

This meant organic and trading day-adjusted revenue growth came in around the 4% level.

But in a potentially negative sign for the broader economy, Adecco's career transition business - which helps companies find new jobs for laid-off workers - said its revenues doubled during the three months to the end of June.

CEO Machuel said there had been a hiring slowdown in the tech sector in the U.S. Still, globally the health and construction sectors remained active, he added, while the automotive industry had strong demand for workers.

"We know there is a lot of uncertainty around, linked to the war in Ukraine, rising interest rates. But we think there is an opportunity to take market share," Machuel said, pointing to the increase in Adecco's sales teams.
