It's somewhat a scam - werkgeversreview Frontend Developer bij Proxify

This is not exactly an employer per say. It's a FREELANCE PLATFORM. Beware! At no point in the recruiting process have they told me this. You only find this information as a 'fine print' somewhere in the contract you sign with them, but this can be interpreted as being a b2b entity. It's been one month now and I have yet to be given any work because they don't have enough projects to go around and get this, they're hiring about 1-2 devs per day!
