Learn English – What does “freighted” mean in the context

Implement software conforming to the specification, fulfilling all its premises. A very common business requirement that also makes (often incorrect) assumption that the software will cooperate flawlessly with whatever it is to be written for.

It's a common short form used in the industry for that. The specification defines requirements the software must fulfill, often in very minute detail. The industry standard definition of correct software is one that fulfills all these requirements.

Of course now whether the specification was correct or not... the unofficial name for this approach is demonology, for wizards who summoned demons had to be extremely precise in defining their wishes, for the demons were extremely literal in interpreting them and given any wiggle space would fulfill them in such a way as to cause maximum harm and grief (but still stay true to the letter of the wish). Programmers writing to specification, especially to bad specification in bad work environment often choose this method of fulfilling the wishes of the customer...

I believe that in this case it means the person who wrote the letter does not know the proper usage of ibid.. The proper usage of ibid. is in a bibliography or footnote to refer to the previous citation.

From the context, I would assume that the writer of the letter mentions the interview in a prior sentence, and now is trying to recall the same information.

For example:

We will be interviewing you on our show "Brightly Colored Morning Extravaganza."
You are requested to appear for ibid interview on Thursday at 7 AM.

Unfortunately, this seems to be the work of a pseudo-intellectual. I know this because, as the adage goes, it takes one to know one!
