I took the maths test in London. 3 rounds of maths tests, starting with 80 easy maths questions but the time constraint is pretty intense. 55/80 is enough to go to the 2nd round. 2nd round were numerical sequences but harder than the one you prepare with. 26 questions from which 20 were enough to go to the final round. 40 questions mixed of numerical sequences (easy) and some a little bit harder maths questions than in the first round. I think 25 were enough to pass this round as well. Note that for the 1st and 3rd round wrong answers give you -1 credit. Also note, that there is a grey zone in each stage which means that you can get one grey zone round and still pass this maths test. All in all not too hard with maybe 1-2 hours preparation and basic maths knowledge. Next round was an HR interview. Also pretty straightforward and just a quick chat about your background. I am waiting for the technical Skype interview.

spent about 1.5 months pretty much purely dedicated to preparing for interviews for all the pre-penultimate programs (Optiver, IMC, JS, SIG, Citadel, etc). I used these resources: Green book (Really good starter but I got bored of it after a few weeks) EverythingQuant (Went through literally every single interview prep question, went through the interview guides, and completed the probability course just to make sure I covered all bases) Briefly read through this guide Watched coding Jesus in my spare time (not sure if this helped directly lmao but he’s a great creator and very informative)
