Pluspunten
They have a great internship program at the company, I would recommend Guidewire for graduates and students on placement. You'll find most of the perks you'd expect at a modern tech company. Good health plan and subsidies.
Minpunten
Compared to the market they underpay for engineers. Don't expect the base salary to match other fintech multinationals. The company suffers from significant bloat in middle management. They seem to need 9-10 levels of management to direct their engineers. The engineering management often have no technical background, they have no context of what you're working on and show no interest. They will ask you to spend your time in workday rather than actually write code and solve client's issues and pull you up on it if you don't.
