Why DoorDash is rebuilding its engineering interviews around AI

For years, software engineering interviews have had a strange relationship with actual software engineering.

The daily job is highly collaborative and involves reading existing code, debugging, writing tests, working across interfaces, and communicating clearly.

Traditional interviews, on the other hand, put candidates in a timed, isolated setting and reward algorithm drills that rarely show up in actual production work.

That mismatch was tolerated because success in those algorithmic interviews was hard to fake and was loosely correlated with computer science fundamentals.
