(...)The better question is, will anyone be able to find and get accepted for any internal jobs posted? I'm sure people will find them, and possibly get interviewed for, but will you actually get hired?
My guess, 5% or less of the impacted employees will apply for internal roles, mainly because the open roles are demotions compared to the roles they're currently in. Probably 20% or less of the impacted employees will even look at the open req's. Of those that apply, 1 in 20 will get an interview, probably for form's sake to check the box that they "tried" to hire internally if audited, and maybe 1 in 100 positions out of the 3K reqs open will get filled with someone internally, if that.
I'd love for the ELT to be "transparent" and tell us how many impacted people's jobs they were able to save by transferring them into a new req via the Talent Migration program.
This is something that interests me too. My guess would be pretty similar to OP's. And will there be transparency? I doubt it.
