"The Two Sigma Opportunity: Using AI to Provide a One-to-One Tutor for Every Student and Teaching Assistant for Every Teacher"
Generative AI has enabled two key changes
(1) We can now work at the level of text
(2) We can more easily work across varying levels of abstraction*
Levels of Abstraction
Words/Text
Computer Memory

Case Studies for Data Science Jobs
During this interview I’ll go over your qualifications, discuss the role in general and the specific research projects and spend 10-15 minutes on a case study. It will be high-level; I’ll introduce a problem and have you discuss your thought process and how you would proceed to solve the question. There won’t be any on-the-spot coding.
