First I received an average coding challenge. Three questions, like the ones you can do in HackerRank. After the coding challenge, I received a technical interview. It was a 30 minutes technical interview in which I was asked to complete a class. The class was about buying and selling stocks. You have to create the function add stocks and sell. With an in/out other of first in last out

Had my Akuna Capital quant dev interview recently — they asked two LeetCode-style questions (an easy warmup and a medium one). I solved both, felt good about it, but still got the rejection email the next day. Tough process, but good practice.
