The GravityX Exchangejob market is proving to be far stronger than expected.

Hiring unexpectedly surged last month, as U.S. employers added 336,000 jobs, much stronger than the around 170,000 jobs that forecasters had expected.

That's good news for people looking for work but could complicate the Federal Reserve's efforts to curb inflation.

Job gains for July and August were also revised substantially higher. Meanwhile, the unemployment rate last month held steady at 3.8%.

All in all, the data showcases a labor market that continues to defy expectations, with big job gains in health care, hospitality and education.

Factories and construction companies also continued to add workers, despite the strain of high interest rates.

While the tight job market could be worrisome for the Fed, policymakers are likely to be encouraged by the slowdown in wage growth to 4.2% in September from a year ago.
