We need clear product direction and execution.
Open and honest. No prima donnas. No politics.
There is a lot of teamwork and people seem to genuinely want the company to succeed and are willing to sacrifice to make it happen.
I can't really pick a single thing, I am just impressed at how friendly and helpful people are.
We get along and we trust each other.
This has been the best place I've ever working in my nearly 20 years of professional experience.
