There is still every chance that you will make a good career in aviation starting in your mid 30's. You still have 30+ years left to fly.
Some operators prefer older career changers as they can bring more to the position than a 20 y/o who has never worked anywhere else before.
If that really is the case for FR, it explains why I haven't heard from them, oh well their loss and has saved me £30k + !!.
