Is it reliable for state-owned enterprises to have no written test and no files?

Not reliable. Formal state-owned enterprise recruitment requires written examination and interview. After passing these two items, retrieve the personnel files of the recruited personnel. Acceptance of personnel files is the key to getting started. Without files, personal resume is invalid, and state-owned enterprises will not recruit employees without files, so it is unreliable to have no written test and no files. State-owned enterprises refer to enterprises whose capital is owned or controlled by the state.
