Both professional activities and hobbies
For example… If a new hire is introduced as “good at Python and C++” at work, what does this imply about the person’s skill level in your opinion? Or if someone says they are a “good runner”, what would come to your mind? Or is it field-dependent?
Asking because sometimes I’m not sure if I am under/over-exaggerating my own abilities when meeting new ppl at work/etc…
You are probably underestimating your abilities.
People that worry about overestimating their skills mostly underestimate their skills.
If someone says they are “good” at something, I take it to mean competency and some enthusiasm.
They might make a mistake, but they won’t (or at least will rarely) make it twice.
They know how to find the solution to something within that domain of knowledge. It might not be the best solution, but it will be a solution that works.
They are also aware of what they don’t know in within the domain. So, they can do C++ but know they can’t do embedded programming. Or they can do C#, but know they can’t do game dev.
And I would take them at their word for that, until they prove otherwise.
If they are below where they claim their skill is, I would try to help them learn (unless they show no interest in improving).
If they are above where they claim, I would tell them this.
It’s always hard to judge our own skills.
