Get that interview process fixed ASAP and let this lemon go. Don’t be surprised if there is pushback from non-technicals if this hire checked a bunch of boxes for other departments. A good strategy would be to have them be a lead on a minor project that requires technical chops and communication. Ensure there is a daily standup and grind them on details and timelines.

This proto-sociopathic behavior is the direct result of European employment law. It's disgusting.
What is expensive in most European jurisdiction to fire a permanent contract after the initial trial period/first year contract without wrongdoing. But that is typically after a year or more.
The reason here is that they are trying to be a employer which focus on personell development. Which is contradictive to capitalism and obviously they have not figured out yet, how to deal with situations like this.
