Marathon Trading interview questions

The interview process was fine nothing unusual 4 rounds about options theory in particular and some brain teasers. There was one round of coding interview as well. You need to have a good knowledge of options and be quick with option math

First round was a Hackerrank, second round was an HR-style screening, third round was a more in-depth discussion of experience. There would have been an in-office round but didn’t make it that far
