Vantaggi
Solid work-life balance. I rarely worked late and all of my projects had distant deadlines. The projects I worked on were pretty relaxed and informal, i.e. a client would ask for support on some project and I'd provide it, no code reviews, agile boards, etc.
Svantaggi
The pay increase schedule is a fairly generous annual adjustment (5-6%) but there's no pay bump for title changes so that's all you get. Additionally, the culture of my team at least didn't really promote career growth or skill learning. My manager gave me a lot of freedom to work as independently, but the tradeoff of that is that I didn't gain experience with code reviews, stand-ups, Agile, etc. Not as important if you already have a lot of experience under your belt but something to consider for a junior engineer.
