I don't work at a bigger tech company myself (so take this with a pinch of salt), but have had plenty of interaction with people who do/did, and I'd summarise broadly: - Salaries are generally a bit higher base than the rest of the permanent tech market, higher still total compensation, lower than the same companies in the US market, and lower overall than the contracting rates which are popular in the London tech market. You will definitely receive a reasonably comfortable and competitive salary, decent pension contributions, shares, and decent holiday entitlement. - The interview process is the same nonsense as anywhere else. - Engineering culture appears to be pretty relaxed. I've heard way more complaints about colleagues who don't pull their weight than I have about companies expecting personal sacrifice. - There are some interesting teams and challenges but the selection is more limited than other markets. YMMV.
