Hi all, I am looking for quant trading jobs.

Can anyone share some of quant interview questions?

here some questions for reference

1. Find x if x^{xx...} = 2

2. 3 points are randomly drawn on a circle. What is the probability of them being on the same semi-circle ?

3. A unit length is broken off into 3 pieces. What is the probability of them forming a triangle?

4. There are 14 identical-looking balls. 13 of them have the same weight while one of them is heavier than the rest. What is the minimum times you can weight to identify the heaviest ball ? How do you generalize for n balls ?

5. The hour and minute hands of a clock meet at 12'oclock. When will be the first time they meet again?

6. Calculate $\sqrt{2+\sqrt{2+\sqrt{2+\sqrt{2+\ldots}}}}$

How much time did you have to solve these questions?

hey can you share the answers as well?

- I got x = sqrt(2) for question 1
- and my answer for question 6 is 2

is it correct?

i think 20-30 min. That is 5 min each

yes i got the same answers

1. Find x if x

^{xx...}= 23. A unit length is broken off into 3 pieces. What is the probability of them forming a triangle?

6. Calculate $\sqrt{2+\sqrt{2+\sqrt{2+\sqrt{2+\ldots}}}}$

For question 5, i got t= 3927.2727...=1 hour 5 minutes 27.27 seconds

can you explain how to get this answer?
