Technical Interview Best Practices: Stop Losing Good Candidates

Your Interview Process is Your Brand

Every candidate who goes through your interview process forms an opinion about your company. A poor experience means losing good candidates and damaging your employer brand.

Common Interview Mistakes

1. Puzzle Questions Stop asking brain teasers. They don't predict job performance and frustrate candidates.

2. Marathon Interviews 5+ hour interview days are exhausting and unnecessary. Respect candidate time.

3. Ghosting Candidates No response is worse than rejection. Always close the loop.

4. Unprepared Interviewers Interviewers who haven't reviewed the resume or don't know what to assess waste everyone's time.
