I am a graduate student in Sweden, and will present my PhD thesis next semester, and have several articles accepted/published.

However, when I applied (and got admitted) I had only studied at the university for three years, and only written a bachelors thesis. Me being admitted was sort of an "error" from the department, (and I had no idea what really was the requirements, since my thesis advisor encouraged me to apply). 

Might this look bad on my resumé when applying for a post-doc position?
(Or is young age an advantage, in my case, 25)?
