I applied online. I interviewed at Hudson River Trading (New York, NY)
Interview
technical coding challenge on codesignal right after i applied, which I had to take within a week, followed by coding interview on zoom with 2-3 leetcode medium/hards after the codesignal. The codesignal I got 3 out of 4 questions correct and the 4th one I just didn't optimize.
Interview questions [1]
Question 1
some system design questions, as well as python knowledge and data structures.
The first round screening was an automated coding assignment on code signal. Had to solve 4 questions in 70 minutes. Classic leetcode style questions with roughly medium to hard difficulty
A *3 HOUR* OA, consisting of both frontend and backend coding
I should have instantly declined to interview upon learning that, and I encourage you too as well.
Felt that I did solid on the backend piece, not as good on the frontend.
