The Interview Loop1 / 3

The loop at a glance

Connect "The loop is one sustained argument" to the decision you would make.

Step 1 of 3

Cursor is hiring one of its first Data Platform Engineers, so the loop is built to find out whether you can stand up infrastructure from near-zero, not whether you can grind LeetCode. Hold the whole shape in your head before you prep a single answer.

The loop is one sustained argument: that you can own the Databricks lakehouse, scale ingestion to billions of events a day and turn recurring data pain into platform primitives, all while the platform is still half-built around you. Every stage probes a slice of that claim.

The paid onsite build and the meal-based values round are Cursor's distinctive moves; the take-home and dedicated design round are standard for senior data platform loops.

Confirm the exact sequence with your recruiter

The onsite build-and-present and the AI-tool policy are well-attested for Cursor. The number of technical screens, whether there's a take-home and the order of the design round vary by candidate and by quarter. Ask the recruiter to walk you through your actual loop on the first call and let what they say override this map.

The full span often runs two to three weeks. The onsite project day is the block that decides it, because it mirrors the real day-one work: scope a data problem under ambiguity, ship a demoable slice and defend the trade-offs to the people you'd sit next to.
