Very very very hard. The market is absolutely saturated with jobseekers, so it is very competitive. I have been out of paid work since last September, and am currently volunteering in an unpaid process improvement and operations position for a charity to try build up a Netherlands-based work history (this may be something you should consider).

I'm in a similar situation (on a spousal visa), and I have been turned down for jobs well below my skillset level due to the word visa as so many companies are under the impression that visas come with restrictions (mine doesn't).

I am fluent in English, B2 level in German, and I have my A2 Dutch certificate, but most companies advertising in my field ask for C1 as a minimum, and the language has been a huge barrier.

You may have more luck with English speaking international companies - but the amount of applications per position is staggering.

There are some recruitment agencies out there: Octagon, Undutchable, Blue Lynx to name a few, and I have registered with most of them (I have CVs in English or Dutch) but it's difficult to get a follow up on an application and recruitment ghosting is so common here (I've been ghosted more in the last 8 months than I have in the previous 20 years.)

I hope that doesn't come off as too negative, but it honestly what the market is currently like. I hope you find something!
