You have three switches in one room and a single light bulb in another room. You are allowed to visit the room with the light bulb only once. How do you figure out which switch controls the bulb? Write your answer in the comments before looking at other answers.

If this were an interview question, the correct response would be "Do you have any relevant questions for me? Because have a long list of things that more deserving of my precious time than to think about this!
If the installation of the circuit was done correctly in the first place, all 3 switches will turn the light on and off.
If they do not, there is a problem and it needs to be fixed. If you don’t fix the issue, you have a major underlying problem in your company. And you are not worth my time.
What is the purpose of having 3 switches next to eachother that all control the same light?
To fulfill the requirements.
The requirements clearly state that only one switch controls the bulb
Must be an earlier revision. The PM just pinged me to add a fourth and fifth switch for “AI”.
