I have launched EigenScore last week; The first competitive problem solving platform for quantitative finance.
You can use it to practice your quant skills, prep for interviews, or prove your skills against other quants in the rated contests.
The first such rated contest is today in a few hours. Join before it’s too late:
https://eigenscore.com/contests/round-1
The problems will range from easy to hard with 3 types of problems:
Standard: Ground-truth problems. You either solve them or not.
Prediction: Better out-of-sample forecast performance gets more points.
Optimization: Better final minimum/maximum out-of-sample gets more points.
Problems come from all kinds of areas: probability theory, combinatorics, portfolio optimization, graphs, and much more.
So anyone can join, no matter your level of experience.
