Pinterest · Software Engineer (New Grad)
Pinterest's new-grad loop is a balanced set of coding rounds plus a behavioral, with a product-and-scale flavor reflecting a large recommendation-driven consumer app. Expect solid medium algorithm and data-structure problems, clear communication, and interviewers who care about how you reason toward an efficient solution. Some loops touch lightweight system or product design calibrated for a new grad. Culture-fit and collaboration are scored, and clean, correct code with good complexity is the baseline.

What this interview tests
- Algorithms & data structures (hash maps, trees, graphs, heaps)
- Clear thinking-out-loud and complexity analysis
- Clean, correct code with edge-case testing
- Lightweight, product-shaped system design (feed, top-K)
- Scale awareness (caching, what grows with users)
- Collaboration and culture fit (behavioral)
Common question themes
Top-K / trending problems using a heap
Tree and graph traversal (BFS/DFS)
Design a simple feed or save-to-board feature
Hash-map, string, and two-pointer problems
"How would this scale as users grow?"
"Tell me about a time you collaborated to ship something"
