I applied online. The process took 5 days. I interviewed at WorldQuant (Austin, TX) in Oct 2015
Interview
Applied online. Got an email from a quant to set up a phone scree. The interview was fairly hard if you do not have a comprehensive understanding of algorithms and data structure.
Interview questions [1]
Question 1
1. Deep copy vs copy
2. Pointer vs reference in C++
3. Global variable vs local variable (how to change global variable from local setting in Python)
4. Find the 3rd largest item in an array without sorting. What about the nth one?
