Goldman Sachs Technology Division - numerical test

Hi,

I'm about to set the date for my first round of interview for the Analyst Developer role.
As I've been told, it will take 1h20min.
From what I've already found around the internet, apart from conversation I may expect numerical and verbal reasoning tests.

Could you tell me what can I expect in such numerical reasoning tests?
Is it (similarly to SHL) based on some chart and table data? Or is it more biased towards probability and statistics?
Do you recommend some sources for preparation ? jobtestprep claims to have some preparation material for GS aptitude tests although it's quite expensive.
Maybe some another reliable source of example questions?

I'm interviewing in Europe but that probably doesn't matter.

Thanks!
