There is a clear difference between US + AU + Asian schools and European schools
US, et all the golden period is 3 years experience. Up to 5 are still OK. Until 7/8 years, you still have chance. More than that, even though you are selected, the programme may not be a good fit for you. There are exceptions. So the virtual age limit is around 27-28
In EU, 5 years is the golden period. 8/9 years is still OK. After 8/9 years, you have very limited schools options. So the virtual age limit is around 30-32
Some schools like IMD, LBS will directly or indirectly or subtly discourage you from applying if you are 30+
Some schools like Cranfield, Henley, Ashridge has quite a few 40+
35+ is quite common in Warwick and I believe a couple of 40+ there.
Having said that, my personal impression is, this year not many people are going for full time MBA and European schools are struggling to fill up their numbers. And due to this, quality of new admits may be different.
