In my (albeit anecdotal) experience, incompetence is the norm rather than an outlier in BigCo SV land.
Frankly, if you are more qualified for a position, chances are you will be rejected because your interviewers will fear for their own job security.
I've always found that type of logic strange, though. Wouldn't you want someone who was better than you currently are on your team? Wouldn't you be able to learn from them?
That only applies if you want to learn. If you just want to coast and be "the best" at something at your company, you dont look for people better than you. At best you look for people that are better at the tech than you, but who are passive or easily browbeat so you can claim their work as your own.
