Would you accept a job offer from a company that wasn't writing unit tests?

I'm fairly new to the programming world (5 months), and I just got and accepted my first serious job offer at a great company. The company is stable, has a small dev team, 20 employees, and is profitable and growing. I couldn't be happier, but.. they don't write unit tests. As someone who sees learning as very important, I wonder if in some ways not writing tests at a company will stunt my growth, future prospects. These days I hear so much about unit testing that I assumed everyone does it, but it seems from some reading on stackoverflow that even as much as 50% or so (this is just a perception, could be wildly wrong) of companies see testing as something they'd 'like to implement but aren't. Would you work for a company that wasn't writing unit tests?
