I'll hire you, payment in wagon wheels only though
Hey bob has a summer job!
20 to 30K in London????
What are you supposed to live on/in?
In this country, your starting salary, as a graduate, "should" be in the high teens to low 20's in the technology industry. You're probably aspiring to be earning £35/40K by the time you're consider "senior" at your role (5+ years on that area). That's minus benefits and bonuses, including holidays (25 days per year, commonly), which add up to rather a lot when you look at paying for them yourself. Probably £50K equivalent at a senior role.
