I have almost 8 years of experience, am currently a tech lead in the company im at (a big known music and video streaming platform), i live and breathe tech...

and someone i interviewed for (in a 4 year old fintech startup) wants to put me in a mid level position because he "felt i lacked depth". apart from his feelings he failed to make me understand how I'm not senior enough for him.

so how do i become deep? what is this depth he speaks of?
