Tips to being a great interviewer

A few guidelines for conducting good interviews:

1. Arrive on time - be present during the interview.
2. Introduce yourself to the candidate
3. Provide a brief intro about the interview to set the expectations for the next hour
4. Always present the question in written form to the candidate.
5. Ask the candidate explicitly if the problem is clear.
6. Avoid giving hints too early
7. If the candidate says terms like the time complexity of naïve solution is bad, ask him to be more precise and exactly define what the time complexity is.
8. Our goal is to maximize the signals we collect during the 45-minute interview. If a candidate solves a question pretty fast in the first 15-20 minutes, make sure the next question gets you some additional signal about the candidate.
9. Don't be biased by your own solutions
10. Be polite and respectful to the candidate.
11. Treat every candidate as if they were a rockstar no matter how the interview is going.
12. End the interview on time.
