Lock the interviewer in the room with three bulbs, when he eventually dies of malnutrition you replace him in the company.

Enter the room and remove the light bulbs. In their place, wire in three distinct speakers that are loud enough to hear from outside the room. Proceed to test each switch and make note of the corresponding speaker tone. Once complete, turn all switches on and lock the interviewer inside.

turn one in for a while, then turn it off, turn on a different one, and quickly go see which of the unlit lights is hot

The funny thing is that this is an interview question for a entry-level janitorial position.

Send someone else into the room with the bulbs and yell through the hallway “Which one is on?” when you flip a switch.

Turn on the switch, then wait for a dad to come around pissed that there's a light on in a room with no one in it

This is an easy one. First, find out who the building owner or facility manager is and get in touch with them. Second, offer to work on their building for dirt cheap as an independent contractor. Third, tell them you need the schematics of their building, then wait anywhere between a few weeks to a few months to get the schematics. Finally, just follow the schematic from the switches to the lightbulbs.

"You may enter the room with the bulbs only once" means you can look inside it a much as you want? Just open the door but don't go in. This is a better solution since the way it's worded doesn't say each switch is wired to a unique bulb. They could all be wired to the same bulb.

As a Google employee, this is exactly why the company banned "brain teasers". The whole "question" hinges on warming the bulbs, something which is incredibly unreliable without establishing specific conditions beforehand and allowing for arbitrary time spent in the first room, and also whether one is even allowed to touch the bulbs in the second room.

It's impossible because a forward thinking company like Google would have invested in LED tech (then you get the job for complimenting Google)

It never says you can't look into the room with the bulbs without entering it.

Very much what I expect from a pseudo Google interview question, undefined parameters that require you to make assumptions that could be wrong without recourse. If we assume the bulbs can get hot, then we can solve this problem easily. But since it doesn't suggest if they do or not, this assumption could be completely wrong.

As far as I know, Google no longer uses such puzzles in interviews, as it turned out that the best candidates are not necessary the ones who memorized countless similar puzzles. But many companies which jumped on the hype train still use them.
