I am working as Junior Developer in a small company, with 6 months experience. Recently, I applied for a job in field I want to specialize in, and declared my expectations as its salary cap (which would be a 15% raise for me).
I have received an offer matching my current salary, and recruiter said it was lowered from what I proposed, due to my review performance. I consider it as a fair argument - I have not answered every question regarding must-have skills.
Job offer includes whole new career possibilities, more perspective projects, interesting technology stack and much better benefits, I would accept it as-is with no doubt. It is a great opportunity for me.
Should I ask for more to have high ground for future pay-rises (or not to be considered a doormat) and how far should I push?
EDIT: I accepted the offer.
