Larger companies tend to rely more on brain teasers in interviews, which can introduce noise, but they often use them as a standard part of their hiring process. Bigger companies focus more on measuring innate ability rather than specific coding skills for their codebase, while smaller companies prioritize immediate productivity in specific technologies like Ruby on Rails.

The technical interview process is flawed; it focuses on memorizing riddles rather than assessing real job skills.

The core problem in interviews is the tension between measuring quick problem-solving skills and the ability to handle larger projects over time. Many of the best programmers have numerous job options, making it challenging for companies that require a trial employment period to attract them.

When interviewing candidates, we assess their problem-solving skills and how they think about trade-offs, rather than just their ability to write code.

The skill that interviews can most easily measure is the ability to think through small problems quickly, but the ability to solve large, complex problems well over time is what you need in an employee.

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.

Google's difficult interview questions attract candidates who enjoy solving tough problems, which is a strategy worth emulating.

Neuroscience provides new tools for hiring by measuring creativity and cognitive performance through engaging tasks rather than relying on self-reported assessments.

Hiring practices must evolve to assess how well candidates can use AI tools, as traditional questions may no longer effectively gauge competence.
