Hiring process consisted of a phone screen and a series of in-person interviews in New York, New York. The phone screen took place with a Human Resources representative that examined my overall background for fit with the position available, Software Development Engineer with the Global Optimization Engine Team. I was then invited to New York, New York where I met where I had four one-on-one interviews (1 in the morning, 3 in the afternoon). The interviews were a mix of skills assessments (background in object oriented programming, data structures, algorithms) as well as personality assessments for fit within the team. Overall, the interviews were challenging (borderline difficult), but maintaining one's composure proves helpful in my opinion...after all, your response to stress is being evaluated as well.
