A lot of the discussion here is treating impostor syndrome and qualifications as binary: You're either qualified or not. And your evaluation of your skills is either above your actual skills or not. But it's more nuanced than that. I'm a Principal Engineer at a FAAMNG company. I have impostor syndrome all the time. Why? Because I measure myself against 1) role models that are ahead of me in many ways - I've always do…
I ask you that because it is much simpler to answer to a binary question like, do I have imposter syndrome? Or put in other words, am I modest?
You can make the link with how people see themselves. A lot of very attractive people tell you they are not very beautiful, and spend their time trying to get validation from others. But they internally think they are the top 5%.
My opinion is a lot of those things exists because people are not honest with each other. So you can't really trust what people tell you about you. And you are always wondering how people see you.
