I&#x27;ve been job hunting lately, and I&#x27;ve faced a few doozies during on-site interviews. It got me thinking:<p>What are some of the hardest technical questions you&#x27;ve been asked during a verbal&#x2F;on-site interview? And how did you go about answering them? Please note the type of job you were interviewing for.<p>------<p>I&#x27;ll start:<p>(This was for a full stack engineering role:)<p>Q: &quot;What is the radius of the earth? Give me an answer and walk me through how you got there.&quot;<p>A: I had no idea. I figured that SF to NYC was roughly 3,000 miles and that was 4 timezones. The whole earth is 24 timezones so I multiplied by 6 to get the circumference of 18,000. Since the circumference is Diameter * Pi I divided by 3 to get a diameter of roughly 6,000 and divided by 2 again to get the radius of 3,000 miles.<p>I googled the answer after the interview, I was off by about a thousand miles. Not bad.
