Do you want to **feel confident** during your interview when **answering a problem-solving question** like:

### "How many times do a clock's hands overlap in a day?"

The key is to show the interviewers that you can **think through problems when you're on the spot.**

## Why Ask This Question?

The interviewer **isn't looking for the right answer!** They want to know **the approach** you used to think through the question and solve the problem.

## Tips On How To Answer

### What todo:

Understand the scope of the problem.

Talk through your thought process.

Answer the question directly to avoid getting lost while solving the problem!

See if there's a clock in the room for guidance.

### What not todo:

Don't blurt out an answer without thinking about it.

Don't say, "I don't know."

Don't remain silent.

Try not to get upset/flustered if you give the wrong answer.

## What Is The Correct Answer Anyway?

Many people want to say **24**! BUT the actual answer is **22**.

**Clock hands overlap at:** 12:00, 1:05, 2:10, 3:15, 4:20, 5:25, 6:30, 7:35, 8:40, 9:45, and 10:50 **TWICE A DAY (AM and PM).**

There's no overlap at** 11:55** because the hour hand is moving closer toward 12 when the minute hand is at 11.

## Example Answer

"Let me** think through **this problem for one mintute. **My instinct is to say 24,** but I feel like the answer is more complex than that.

**Let me talk this out**...the clock hands would overlap around 12:00, 1:05, 2:10, 3:15, 4:20, 5:25, 6:30, 7:35, 8:40, 9:45, 10:50, and 11:55. That is 12 times, but it would happen in the morning and night, so the answer is 24.

Actually, now that **I have thought this through**, the hands would not overlap at 11:55 because the hour hand would be moving toward the 12. So, the answer would then be 22."
