That's fantastic news! I'm proud of you - it sounds like you've landed an excellent opportunity to gain skills that should set you up for life.
And bear this in mind: you can get all the advice in the world from old sods like me who have been there & done that... but at the end of the day it was
you who convinced the recruiter that you would be worth their time & investment.
You were the only one in the room selling your skills. So you deserve an enormous pat on the back.
Well done!
