Google Code Comprehension Mock Test

Practice code comprehension in a 75-minute, AI-assisted mock test. Investigate three reports, explain your findings, and verify fixes. Independent Google-style practice.

What does this code comprehension mock test assess?

You work in an unfamiliar codebase: reproduce reported behavior, trace relevant code, explain what the evidence supports, and verify targeted changes. This is independent Google-style practice, not an official Google assessment.

How does the mock test work?

You have 75 minutes to investigate three debugging reports. Read a report, inspect the running application and captured logs, then review relevant source. Explain your finding before making a scoped repair.

Can I use AI during the mock test?

Yes. The in-product AI helper can inspect source, run experiments, and help implement an unlocked repair. You are responsible for interpreting the evidence and checking the result. Work individually and leave outside AI tools closed.

How is my saved work evaluated?

Your saved work is evaluated automatically when you submit or time expires. Checking a finding unlocks that ticket’s repair; it does not submit the assessment or prove that the repair passes evaluation. You can submit partial work.
