So I gave the online assessment for Explore HRT, which is a 2-3 day program by Hudson River Trading for sophomores to get a hands on experience into how HRT works and learn about the field. There were 4 questions. I solved 3 and got 10/20 cases

passed for the 4th but didn't have time to debug the last one because I misread the 3rd question and kinda wasted some time finishing it. I received the rejection mail but that got me thinking do they only proceed with people who get a perfect score? Do they consider factors like resume and location as well or is it basically an expectation to have a perfect score. I've seen some friends apply to Citadel get a full OA score but still get

rejected, would that be because of location (it was in a different country but still nowhere was it mentioned that it was restricted for internationals).
