I'm a good-enough software developer. I've worked with folks who are better, but I deliver working code that follows best practices and have been very useful in dealing with a lot of very difficult technical problems including dealing with reading and fixing kernel panics in network device drivers (early in my career) and also working with big data scale backends. Everyone who's worked with me has positive things to say about my professionalism, abilities, teamwork, etc., including a director of engineering I reported to for one job. I'm working for a FAANG now and my manager's manager is checking in to make sure I'm happy.

I interview terribly and can go for long streaks of interview flare outs, and hit the same thing she described - I'll blank on things that I would be able to say effortlessly in a non-interview context, even when I'm fairly relaxed. Being good at software engineering isn't the same thing as being good at interviewing.
