Pinterest Data Scientist interview experience

The coding portion leaned on basic data structures—things like strings and arrays—then added additional coding questions tied to machine learning topics. Alongside that, there were multiple-choice questions that were overall on the easier side.

What surprised me was how quickly it moved from fundamentals into ML-flavored problems. The “easy” MCQs didn’t feel like a warm-up so much as a pace-setter, and the real challenge came from switching mental gears between standard data-structure manipulation and coding tasks that assumed I could reason about ML concepts.

I didn’t make it to the later
