Companies often look for different qualities in engineers, which can lead to confusion. It's crucial to clarify the specific skills and traits desired for the role being filled.

No engineer passes all their interviews, highlighting the inconsistency and noise in the interview process.

When hiring, it's important to identify the conscious decisions about the type of engineer you want, as different companies have varying needs based on their culture and goals.

The obsession with hiring as many smart engineers as possible, regardless of the company's needs, became a common practice among startups, reflecting a superficial understanding of what truly drives success.

A significant source of noise in the hiring process comes from companies being inconsistent in their interview questions, leading to a gut call that can misrepresent candidates' abilities.

There's a huge amount of noise in the interview process; candidates who do well at one company may fail at another, and the agreement between interviewers can be as low as that of movie reviewers.

Even if engineers are better at evaluating other engineers, the existence of recruiters suggests there are efficiencies in the hiring process that are not immediately apparent.

Companies typically make offers to only 2-8% of all engineers who apply, with significant variation in where candidates drop off in the hiring process.

Engineering interviewing is a field where many common beliefs are misleading; for instance, evaluating past work does not predict job performance as effectively as practical programming assignments.
