Volant Trading Quantitative Analyst Interview Questions
& Process

Applied online about a month ago and got a notification for a timed coding challenge. After I passed that, they scheduled a phone interview. However, the phone interview got rescheduled because the traders I was supposed to talk to were suddenly unavailable. The phone interview eventually happened, and I was asked an algorithm question. I didn't provide the best solution, and the interviewer seemed annoyed and passed me on to someone else to continue. It was a really bad and disrespectful experience, unlike my other 10+ phone interviews.

I applied online and heard back a week later via email to complete a C++ coding test. It was two and a half hours long with three coding questions. I solved two of them, but the third was quite difficult. Although there was only one test case shown for each question, I assume more will be used for evaluation after submission. We were allowed to write our own test cases to check our code before submitting.

got an online coding test from cordiality, it was standard and not that hard. it took about 2 hours with 2 problems, basically to check my skills in Data Structure and Algorithm. The first problem was about vectors and the second was about vector of vector. I thought it was easy, but didn't hear back after submitting.
