I applied online. The process took 3 weeks. I interviewed at DV Trading (Chicago, IL) in Oct 2022
Interview
I had a call with HR and a call with the lead trader. Discussed experience and explained what the role would be like. Overall not bad, but did not meet the criteria for what they were looking for.
Initial online maths and probaility test, Normal screening interview followed with a final interview with a senior trader on the desk which was behavioural and technical.Advice is to brush up on typical quant interview resources such as the green book.
First round is behavioural. Second round has 4 brainteasers. Interviewers are friendly. but the brainteasers are pretty challenging. i didnt get enter the on-site round. But overall experience is pretty good.
