Review this Go validation that records each failed check for a metrics counter, then decides whether the request is valid.
What a strong answer looks like
Separate real bugs from style. Rank issues by severity, point at the root cause rather than the symptom, and suggest a concrete fix — specific and kind.

func validate(r Req) bool { return recordIfBad(checkAuth(r)) || recordIfBad(checkRate(r)) || recordIfBad(checkSchema(r))} // recordIfBad returns true when the check FAILED, and increments a per-check failure counter.func recordIfBad(failed bool) bool { if failed { failureCounter.Inc() } return failed}Run or narrate your approach, then ask the coach.
