Interview Guides
You are supporting a client who calls a Moody's API and gets a successful response, but the returned dataset looks incomplete. The client says the request parameters are valid and the HTTP status is 200, yet some expected records, fields, or time periods are missing. You need to determine whether the issue is in request construction, source data availability, transformation logic, or the way the client is reading the response.
How would you investigate a client issue where an API call succeeds but the returned data looks incomplete?
