I've noticed a common theme across several such posts/comments - our definitions of a "good" company can widely differ. I, for one, find it's important that the team can always quantify how every feature adds value to customers. Others are happy just focusing on highly-technical, challenging work.

We're already starting to see examples of these differences in the thread started by @JonChesterfield; I'm sure others will pop up.

The only conclusion I can draw so far is that interviewing the employer remains as important as ever. Don't just write off a company because of what you see online, just have a 30 minute chat.
