So, can you provide a hint? The forum is supposed to support others in the MS community. This feels like a mean girls club where you are intentionally whispering to the in-crowd and shutting out everyone else.
Obviously, I did read the thread thoroughly. What I gleaned from my reading is that at least half a dozen people have inquired about to get these and not one of them got a legitimate response. You said yourself these are not posted on job boards which still leaves the question of how do people get these?!? Honestly, your response was not helpful at all. @myst4au is right, there is a lot of "gatekeeping" happening here. Are they too good to share? And if so, then just say that. If not, can you actually explain what you mean? I have never seen these from the MSC I am assuming does these. I read the thread. It does not contain an answer.
