Learn English – Is it grammatically sound to group nouns/verbs sharing a preposition that governs the same object using an “and” multiple times in one sentence

For example, does the following sentence violate any grammar rules?

"Global Connections" will be showcasing internship opportunities, job openings and training programs at, challenges and issues facing, and the latest information on 30 leading global businesses.

I realize that there may be alternative ("better") ways of phrasing the above but I am not interested in improving this specific sentence; I just want to confirm whether the above structure is generally permissible according to the rules of English grammar.

I would like to emphasize that I am not looking to have the above example sentence proofread. I would like to know, first, whether it is acceptable to group nouns sharing a preposition in the fashion that I have and, second, whether it is acceptable to do this multiple times (i.e. for other nouns affiliated with other shared prepositions) in the same sentence. My gut feeling tells me that it constitutes an over-usage of "and" in the same sentence but does not specifically violate any grammar rules. I would like to know for sure whether this is the case or perhaps there exists some grammar rule I am not familiar with.

I'm going to stick my neck out and say that there's no grammatical rule that disbars OP's example.

But it's appalling English, which can't possibly be endorsed. It's like saying...

Buffalo buffalo Buffalo buffalo buffalo buffalo Buffalo buffalo

...is a suitable way of expressing the two statements...

Those buffaloes from Buffalo that are intimidated by buffaloes from Buffalo intimidate buffaloes from Buffalo.
Bison from Buffalo, New York, who are intimidated by other bison in their community, also happen to intimidate other bison in their community.

It's English, Jim, but not as we know it.
