I am working as a freelance designer and lately I've been trying to make my process more well defined. I'd like to know what the process is for designers at large companies like Facebook, Twitter, etc.<p>Are there any designers who work at large tech companies who might be willing to share?
I'm not sure what it's like at super large companies, but I agree with another comment that assumes they make decisions based on micro-testing interactions with their millions of users.<p>At a mid-size company I worked at, we looked at metrics using analytics software (like Pendo and Full Story, not GA) and then AB tested variations to see if they moved users to our desired behavior.
I'm particularly interested in how you do about understanding the problem in more details, brainstorming solutions, working with your peers and getting feedback/review, and finally what the final set of deliverables are.
