I've seen it recently - a guy in extended family who is hardcore introvert to the point of being very annoying in family settings (yet leads a small team of devs) wanted a promotion and eventually got it.
He got overly stressed from all the extra responsibilities, and after few months asked to move back, while everybody told me he did fine job.
Here is the thing - he still wasn't ready/good fit even if at glance all seemed fine. Its not just raw skills that make you a good fit for such a role, its the whole package, and how you manage long term while not going crazy. He was simply too junior for that role, even if from whole palette of skills only confidence/'maturity' (lacking proper word here, non-native speaker) was lacking. That was enough.
He will get there eventually. No point pushing hard for position that somebody may even give it to you, if it eats you alive (he kept elevated salary though... multinational corps are often weird)
