Google·Software Engineer·Online Assessment (OA)
Apr 2026
Got recruited for a software engineer role at Google and the process has multiple stages: a behavioral group hiring assessment, virtual onsites covering AI/ML and culture fit, then in-person coding rounds if you make it through. Right before the virtual onsites, an unexpected online assessment invite showed up with no real explanation, just a vague 'optional' label from the recruiter.
- Does performance on the optional online assessment actually factor into the hiring decision?
- What happens if you skip the optional online assessment entirely?
- What is the difficulty level of Google's optional online coding challenge?
“The recruiter called it optional but that word does a lot of heavy lifting.” The rest of the author's notes on Software Engineer interview at Google, Online Assessment (OA) round, covers how they worked through the question, what the panel pushed back on, and what they would do differently.
