Baseten Interview Questions
We track 3 interview questions reported from Baseten: 2 in Coding & Leetcode-style Questions, 1 in System Design for ML. They average 3.3/5 difficulty — medium for a working engineer — and every one was reported by someone who sat the loop, not written by us. The topics that come up most: parsing, string, stack, recursion. 3 were reported asked within the last year — most recently October 2026.

Reported Baseten questions
Single-Pass S-Expression Parser with Error Positions
3/5Build a hand-written parser for a Lisp-like syntax of numbers, names and nested parentheses, scanning the text once. The hard part is precise error reporting: which mistake is found first, and at which index. A last stage pushes nesting far past the interpreter's recursion limit.

4/5A system design round about the full life of application logs, from a client library inside each service to storage that engineers search during an incident. Expect back-of-envelope sizing, a storage layout chosen for the queries that matter, and clear answers for outages, floods and runaway queries.

3/5A two-stage bit manipulation exercise: build a tiny deterministic random generator out of shifts and exclusive-or, then turn its output into a stream cipher for a nested document. It checks 32-bit masking in a language without overflow, canonical serialization, and strict failure on a bad key, and it ends with why such a scheme is not secure.
