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.

The best engineers typically pass about 80% of their interviews, indicating that failing some questions is common and not a reflection of overall skill.

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.

Most companies think they are trying to hire good engineers, but their definitions of a good engineer vary significantly, leading to noise in the hiring process.

Interviews are the worst way to evaluate engineers, except for all the other options available, so it's essential to make the interview process as accurate as possible.

To screen and evaluate engineers effectively, leverage your experience and insights gained from interviewing candidates.

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.

Candidates who answer questions easily tend to be better engineers, but there are also false negatives where great engineers may struggle with questions.

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.
