I'm in my mid-40s and have just completed a career change - gained an MSc in a completely new field of work and got a place on a graduate scheme to learn more skills etc.
I started the scheme in April and it's been great, however I am quite conscious that I'm older than most of my colleagues while being the "junior" but it hasn't bothered me too much, I knew I needed to take a step down to get back up. However, I've also avoided telling most of my colleagues exactly how old I am - and it's quite clear that they think I'm about a decade younger than I am. (They're mainly in their 20s and therefore think everyone over 35 looks the same!)
All the other graduates are starting in September and yesterday I received an email asking us all to write a profile of ourselves- it was quite pointed that we needed to answer every question. The first question is "name and age". AIBU to feel really uncomfortable about this? It's a tech field, so there's a bit of imposter syndrome playing into this too, I just don't want to feel like everyone's mum/gran!
