Algorithm (coding) requirement for Quant Interview

Hello all,

I am a prospective MFE student and I have some questions for the preparations for quant interviews.

1. To prepare the algorithm part, some one suggest me using LeetCode. Could anyone tell me that what topics are frequent in the quant interview? Since I think quant is not SDE, it's not necessary for us to master all of the topics. Or, is there any other resource that is helpful for preparing the algorithm part of the interview?
Topics in the LeetCode:

2. When I do the algorithm problems, it's better to use python or cpp? For me, python is easier to use. But, it seems that cpp is still important for traditional quant.

Thanks!
 
If you know C++ algorithms the you probably have better insight into the internal than with Python which is more high level.

Thanks, I also believe that C++ is better to practice the algorithm.
For the topics in LeetCode, could you tell me what algorithms or topics are important for quant interviews?

Most of them are relatively easy. Let me suggest you to learn Red Black Tree and all its operations. The implementation in C/C++ is another story
 
RB Tree in Boost C++
Class template rbtree - 1.58.0

There are different levels

1, Understanding how to use
2. Applying and customising; knowing internals.
3, Integrating into applications. Writing your own b tree in an emergency (or buckets of time on your hands).
