    Easy Interview

    Application

    I applied online. I interviewed at Jane Street (New York, NY) in August 2017.

    Interview

    Emailed an excel assessment and a case study about applying regulation snippets for haircuts. (You don't need any background research for this). Please notice virtually ALL their interviews on glassdoor have "no offer". I think this is a small company that sends out these assessments with no real jobs available. I spend 2-3 hours on their tests when i was pressed for time and in retrospect that wasn't worth it. (I'm an expert in excel and am 100% confident i got everything right - and still no offer).

    Interview Questions

    • Applying haircuts, using sumifs, countifs, and sumproducts formulas.   Answer Question

    My interview only lasts 15 minutes. The HR introduces the role and then jump right into three mental math questions. The questions are pretty easy. I spent about 10 minutes on that.
