Coding (Platform)
A cross-layer workflow passes unit tests but breaks when client, API, and persistence state arrive in a different order. The affected area is service gateway.
Repair the service gateway input boundary implementation so it normalizes valid records and returns field-level errors for invalid ones.
This coding (platform) exercise trains the same sequence expected in an interview: understand the prompt, make assumptions explicit, produce a concrete answer, and explain the decisions behind it. The task is marked easy difficulty. The private workspace adds the tools required by this round, such as recording, code execution, diagrams, evidence panels, or structured notes. It also preserves the attempt so later feedback can be compared with previous work. Evaluation is based on task-specific criteria and the candidate seniority selected in the preparation path. Public pages never expose the reference solution, hidden tests, evaluator instructions, or another candidate’s work.
