Can you call a brokerage and ask them if there is a 401k match for a company and how much?

When job hunting I’ve had almost 0 percent chance of getting this information from employer or contracting company where I may end up working full time someday.

It’s obvious that if they don’t want to divulge this information it’s prob nothing or small like less than 6% match.

If you find out what brokerage it is can you call the brokerage and simply ask what the match policy is?

Edit: are some of you responding 60+ or are about to enter the job market?

The last four jobs I’ve had have all been contract to hire.
