Preparing for interview process at Flow Traders

Question

Got selected for a math test at Flow Traders. I get about 65/75 in 10 minutes @ TraderTest (custom, one operation). What are my chances? Has anyone else taken it?

I just had my personal interview. Must say it was tough. There were few puzzles which i was not prepared for. 2-4min time for each. 
1. Draw a triangle made up of 9 circles, fill each circle with numbers between 1 to 9, do not fill the same number twice. Fill the numbers in such a way that when you add the sides, each side should be 17. 
2. You have two hour glasses a 7min and 4 min ones, calculate precisely 9 min.

Further there was a question about how will you price an ETF tell us the formula.

All this for a personal interview with the HR.

bumped!

If i remember correctly flow traders test was a bit different to the usual optiver type test.

There were no fractions or anything of that kind. Just three levels of questions (the third being  ridiculously hard but weighted so they were worth more).   First section is easy eg. (686/7). Last section is like 44,996 / 14 (but this part is multi-choice).

Thanks for posting the puzzles. Here are the solutions:

Question 1:

The triangle drawn as above. Let the vertices' values be A, B and C. Since the sum of values of each side is 17, and we are overcounting the vertices twice, the equation is 3x17 - A - B - C = 1 + 2 + ... + 9.

We get A + B + C = 6. So A, B and C can only be 1,2 and 3 (in any order).

In regards to the other question, it doesn't stop you if you don't have the right answer, so on the flow traders one you CAN skip a question if it's taking you too long.

If i remember correctly there is no decimals. But what i meant by no fractions is that there are no questions involving fractions. Eg. in akuna and Optiver tests you could get questions like (5/7 x 3/4). There are none of these on the flow traders test.

40 is okay but i would keep practicing as much as you can before the test.
