I think you have answered your own question.
You are applying for a job which will see you as a long haul wide body captain in 3-6years and you state
I dont want to be a leader
I recommend you sit back and think about that, and what you percieve is the role of a captain of an aircraft that has 18 (or more) crew members.
Then put yourself in the recruiters position and imagine what he might be looking for.
As far as age goes i suspect you are more likely to be too young rather than too old.
