I applied through college or university. The process took 6 weeks. I interviewed at Athena Capital Research (New York, NY)
Interview
There were several stages to the interview. I first had a two-on-one interview after our Fall Career Fair, a two-hour remote coding task in C++, and day-long onsite in New York. The onsite lasted about five hours, and consisted of several one-on-one interviews with about 5 engineers and their HR rep.

Given a graph of a stock price over time, write an algorithm that finds the best time to buy and the best time to sell if you can only buy and sell once.
