What is it with the obsession sending applicants to the DLR/Interpersonal in EASA counties?

​

I am currently looking for a job in the EU after converting my FAA license to an EASA one. The reasons for that have already been discussed in a previous post.

Every airline I've applied to in Germany, Luxembourg, and Switzerland wants to send me to DLR or Interpersonal to take a psychometric exam.

So far, no one has actually cared about my total of roughly 4,500 hours, 2,500 of which are on the Boeing 737 NG and MAX as a first officer. They all want me to take one of these tests before proceeding to the simulator stage. I have never heard of or had to do such a thing in the US before. The only one who did not ask about such a test immediately was Air France.

So, what's the problem with these tests? Why are the airlines I applied to so obsessed with them that they don't even invite you to an interview before you pass one? The only thing I've heard about them is from a former colleague who switched to the EU and ranted about how stupid he found these tests. He said it was a massive waste of time.

I understand why airlines would put fresh cadets or soon-to-be cadets through such an exam, but I don't understand why they would do it to seasoned pilots.
