Optiver Junior Trader interview questions

Get a phone interview through campus career fair (calculate simple math questions, I think acceptance is based on correctness and efficiency, this part is not hard), the phone interview asked about behavior questions like why do you want to be a trader, how do you know our company, what books do you read, etc.

I applied on the website - 2 weeks later do a math assessment and after a week got a behavioral interview. A week was the trader interview. Round 1 - Math Assessment - 80 simple math questions in 8 minutes Round 2 - Behavioral phone interview - fairly easy, competency based and basic fits questions Round 3 - Trader Interview - brainteasers/logic questions - all technical based Didnt move on after third round
