What are the unwritten responsibilities of being a senior developer?
E.g. even if you're just discussing an idea or making a suggestion, your words have extra weight and some people will find it hard to disagree with you.
Keep in mind it's a made up term by your current company and no qualification whatsoever. And so it varies a lot between different companies what the meaning of the word senior is!
Senior there, junior there, no title/rank there.
Sincerely a CEO of my own company :p
