In the UK software engineering industry, how common is it to find a business with an open or casual dress code? What is the norm in these businesses?
I'm currently job hunting and finding that most often the dress code is business casual (or smarter/more formal)*. My last job, however, had a casual dress code, outside of meeting with clients, so I'm now wondering how common that is.
*I don't ask about dress code, but about office culture and the answers tend to end up including dress code.
