To be contrarian, I'll point toward financial engineering (not retail or I-banking and such) such as Renaissance. It takes some pretty crazy and smart people to dig into FPGAs and HDLs trying to write what would normally be CPU based algorithms while focusing upon latency and availability as well when so many dollars are in motion. The industry's secrecy habits make it hard to get a fair assessment, but I've never heard of anyone incompetent at such a place while I've heard gobs of stories of incompetent people at large tech companies.
