I dare anyone to go look for a promotion opportunity on ODW that is within you realm of knowledge/role (the next IC level) and, I'd bet money there are plenty of open positions in other countries... Just not here in the US.
In my org last year, of the 800 or so employees, 99% of promotions were overseas - India, Ireland, Slovakia, Mexico, etc... and maybe 5 in the US. I'd say I'm baffled as to why but I'm not. A single promotion in the US can be used to promote 2 or 3 people in another country for 1/4th of the cost. Which is BS.
They are too cheap to promote the REAL employees simply because they choose to cheap out and NOT promote US employees. HQ is literally in the US and I'd bet very very few of them have been promoted in the last 6-8 years.
What's hilarious is that they act as if being remote is a "disadvantage" because you aren't illegable for promotion or internal movement. Yeah... well, apparently NOBODY else is either if you are in the US.
They take open positions/backfills and literally repurpose them for cheaper countries.
