I'm a recipient of freshly graduating (and interning) engineers who got past the hiring committee.

The project roadmap puts a burden on the other team members when one member is underperforming and/or not forthcoming with their abilities.

I care if engineers fake the learning required for their degrees because I don't want to cross bridges that collapse, take airplanes that crash, live next to leaky or explosive industrial facilities, or rely on faulty medical equipment. Engineering carries a lot of responsibility.
