As Sidi has said, it depends on the regions/locations.
In Italy, it has not been used for 3 years now. I know it is the same for Spain.
Instead of the PST, in Italy (but I believe it's the same in all countries that don't use PSTs), there is a super easy timed online test divided in two parts:
- Text comprehension: 5-line texts and a question where you have to answer "true", "false" or "not inferable" - it's roughly 30-40 questions, but you have plenty of time to answer
- Maths/graphic understanding: problems like currency conversions, graphs understanding, logics - also 30-40 questions, here you have to speed up, because the time is not so much
If you are in doubt, you can ask the recruiting person when they reach out to you to schedule the PST/online test, to understand how to prepare. They are completely different tests.
If you have a pretty good idea in which geography you would like to apply, I would suggest to reach out directly on Linkedin to the HR people or a few consultants (better if new-hire or <1 year tenure so they would be updated on the last "recruiting trends") to ask them directly and prepare accordingly, since the PST is a pretty tough test.
Hope it's useful!
