My title is senior application engineer. I don't think I've ever actually said that out loud. I just tell people I'm a developer. Titles are meaningless beyond letting HR know what salary band I should be in.
Yeah, same here. I was excited to get the promotion, but when people ask what I do for a living, I typically say "eccentric" for a more casual conversation, and "software engineer" for something more serious. I realize now that if you have to rely on titles for people to take you seriously, you probably aren't making great points.
