Did a HackerRank test for the quant position. It had a coding section with 2 questions and a math questions with around 11 questions. The coding questions were mostly around leetcode medium, and didn't take that long to finish in Python. However, the more difficult part was the math test. It includes topics such as Linear Algebra, Probability, Statistics, Calculus, so I'd suggest to brush up on these topics before taking the hackerrank. I did not pass on to the next portion.

oa, hirevue, and superday. it was very easy, simple leetcode tagged questions. i found out about it through a school event. going to their sponsored events are helpful, having a referral helped me get the oa.
