An interviewee at UBS for a maths-heavy quant job was asked one of the toughest Wall Street interview questions we’ve seen yet.
Can you write your own maths formula given a set of conditions on the spot?
If you want to be a quant at UBS, you’ll have to.
To test your skills, try to answer this question posed to an interviewee a couple of years ago:
The number 1978 is such a number that if you add the first 2 sets of numbers, you’ll will get the middle 2 sets of numbers. So in 1978, 19+78=97; so the question is write a formula that can find numbers that satisfy these conditions.
Have fun! We’ll post the answer next week.
