At what age are you a junior developer and at what age are you a junior psychiatrist in NL? A bachelor's developer could be as young as 21 I guess, but at least for most jobs in medicine you can't work independently until much later. Maybe it's different for psychiatry?
It's not different for psychiatry. You need to have done a bachelor + master in medicine and on top of that a specialization. I don't know how long that takes though, but I wouldn't be surprised if it's 8+ years.
