How to evaluate the UX maturity of a company

I was presented with this opportunity in the summer of 2015. Until that point, I had spent two years living in Germany and working for an early-stage startup in Luxembourg. It was the job that I moved abroad for. Now, I finally had the chance to move to London and kickstart my UX design career there. Or so I thought. The gut feeling that I ignored was right. I joined the London-based startup which described the role in the contract as just “designer.” I found it odd at first, but then I consoled my self with something like: they probably see designers as generalists, that’s why they didn’t use UX designer or Product designer to describe the role. Being self-taught and having mostly freelance and early-stage startup experience at the time, I had already considered myself as a generalist. So I deluded myself that calling the role just “designer” was actually a good thing.
