All salaries data from my current company + [Counter] offers from other companies for people who are either joining us,leaving us or being poached. Nothing I can publish I'm afraid ^^
It ranges from junior out of college to senior with many years of experience. That only includes people who can FizzBuzz though.
IMO: I'm a firm believer that anyone with a clue who's offered 35k£ for that kind of role should just stand up, thanks the interviewer and leave.
