32 is not to old, I was 30 when I started in the IBEW apprenticeship, there
were two guys older than me and there was one a couple years ahead of me
that was 50 when he started. Ask why you were not accepted. If it was
because there were more qualified applicants than they had positions for,
you can try again next year. If you couldn't pass the apptitude test,
then study. Be careful with the IEC program they don't measure up!!
