i don'tthink so but you do have to pass the assessment like any other candidate. Do be aware that the older you get the harder it becomes to learn things and airlines do take that in to consideration (adversely but never officially).
When I did my TR last year it was the 4th one I did (aged 43) and it was not easy, even with solid previous experience. A chap on my course was slightly older than me and was a cadet with low hours. Unfortunately he didn't make it through the course but it was the sim that got him rather than the theoretical stuff. You have to be able to think quickly and learn quickly. The sim is there to practice what you already learned. I think it was the basics that let him down. This is the exception by the way.
good luck, but don't spend a cent on a TR until you have an absolutely guaranteed job offer. In writing and witnessed by the Pope.
