I applied online. I interviewed at Optiver in Aug 2025
Interview
Online Asessment: Rapid Fire Probability
Questions + Brain Games. Really tested the ability to process numbers very quickly and then also to see how the brain works. They are looking for a certain type of person.
Interview questions [1]
Question 1
What's the probability that given a random number from one through one million, that the digit 7 appears at least once in the selected number.
Very smooth, the HR just asked me why Optiver, why quant, what is your strength and weakness, what is the career plan in the next 5 years, but I did not answer very perfect
first round of math probability
2nd of betting. the platform was bit hard to use. Recommend to get some training if you can find the resources. both interviewers were nice
The first section was the online assessment which wasnt too bad, and the next part was a scheduled face to face behavioural interview. Still waiting to see if i passed that stage of recruitment
