I can confirm around 100k (pounds) in London, unless you're going to the giants (FB, Google) that go above that.
(I make 6 figures in London, and that's full time and at a software company.)
I just don't believe I somehow missed all the decent jobs during a lul either.
Head out of finance and tech (funded or profitable) and those numbers start to look more like senior salaries.
Their offer total compensations significantly above 100k£
Until I read your comment, I had guaranteed myself never to work for a UK company. Will need to do some more research at some point.
