I applied online. I interviewed at Optiver (London, England) in Oct 2022
Interview
Online Assessment and HR Interview. The HR is really arrogant and mean. Lack of respect and no matter how well you prepared, if you don't coincidentally meet their answer, they will reject you.
Difficult, need to prepare for the mental maths definitely. You can prepare using several online tools but take some weeks. Didnt make it further than the first round of online assessments though.
I applied online. The process took 4 weeks. I interviewed at Optiver in Jan 2023

Interview questions [1]
Question 1
Say we fire you after one year, what would have been the reason?
Just like a normal behavioural interview. Have been asked questions like Why are you interested in quantitative trading and what is ur greatest achievement so far. HR was nice and ask questions based on your answers.
