Should you want to apply for the recognition of subjects, please consider the following aspects:

Industrial experience prior to the start of your Master study mostly cannot be recognised as an internship. This is due to the regulations stating that this experience has to be gaind within a German company in Germany or at least in Europe.

Even if modules of your Bachelor overlap or are even identical to a Master module these will not be recognised. This is due to the fact that your Bachelor degree has been used for admission and may not be used twice. In case you have studied some Master courses eleswhere prior to your Master studies at RWTH this may generally be accepted. In this case please first contact the respective institutes responsible for the modules of interfest and check if they will state that both are equivalent. Then submit an application to the board for those subjects that fulfill this requirement.
