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!
What about trying to figure out first what the other two buttons do? Maybe they turn on the light of the room you’re in. And I can see light without entering a room right? Just open the door, no need to enter it. If not allowed, look at the foot of the door or try to see if the room has a window.
No need to buy fancy equipment or even go into the room at all.
I’ve seen Rick and Morty. I know what they do. Grab a shovel.
You’re assuming they don’t control something in the room with the light, or they could control the lights in your room and the light you’re trying to check .
Ah yes.
The infamous “they” who control everything.
But what “they” who control “they”, who are really in control of the lights in your room and the lights you’re trying to check?
What if there’s an infinite amount of “theys” all the way down that by mathematical logic leads to myself?
What if the interview being held and the question being asked wasn’t meant to test me, but to test you?
What then?
By “they”, I meant the switches.
But I’m just a brain in a jar and you are a simulation implanted in my consciousness by the switches so it doesn’t really matter.
