Technical Coding
After my CV was screened, I got sent a proprietary online assessment with 10 MC questions. Some were unusual, some were tricky, but most were standard quant brainteasers you can pass if you've done a lot of practice. Then, there was an online interview with a quant who asked me a barrage of technical questions. The bar for passing probably depends on your answers and how many you get right. I wasn't prepared for some questions and totally fumbled.

Coding Technical
The interview involved solving a medium-level LeetCode problem using a greedy algorithm, where I had to write efficient code, analyze its complexity, and talk about how to optimize it. Then, there was a statistics problem where I had to analyze a given scenario or dataset, use appropriate statistical methods, interpret the outcomes, and discuss my methodology and conclusions.
