Is it permissible to apply with certificates obtained through self-assessment or without examination?

The deception and fraud committed to obtain the certificates are not approved by Islamic law, and one must repent from them by feeling remorse and resolving not to repeat them. If the current job is a result of these certificates, it is another deception from which one must repent. You are not obliged to leave the job if you are performing it as required, according to the testimony of specialists; otherwise, it is not permissible to continue in it. It is not permissible to apply for another job using these administratively invalid certificates, even if you are capable of performing the job.
