Bad hires can bring down software quality, cause problems, and lower team morale, potentially even impacting the survival of a small company.
💻
"Coding is necessary but not sufficient companies are looking for people that can contribute meaningfully to projects that take many people potentially years to complete for fan companies."

🤔
Companies avoid asking leadership questions in a situational manner because it's easy to answer abstractly, making it important to ask behavioral questions to truly gauge a candidate's leadership skills.
💼
"Leadership without authority is really hard to do. It requires that you have the technical chops to contribute meaningfully to big projects."
💻
"Most tech interview prep is garbage because it doesn't focus on the actual skills needed for the job."
