DE SHAW - SMTS - Application Engineer
Summary
I had a fast-paced Hackerrank Code pair interview for an Application Engineer role at DE SHAW, which felt like it could have been two rounds. The interviewer was very chill, and the experience covered various topics including behavioral questions, system design concepts, a specific LeetCode problem (1413), and React-specific questions like implementing an add-to-cart functionality.
