Give each prisoner a number. Tell them if one tries to escape, you will shoot the prisoner one number above them. 100 is tied to the 1st. Ideally, each prisoner keeps the prisoner below them in check.

This is a good premise, but it assumes they won't communicate what their numbers are. Any number below the initial escapee is safe to leave.

Assuming that they do not know how many bullets you have, you have them line up in rows. You tell them that if one person on their row attempts to escape, everyone in the row dies.

Grant them all their freedom. Nobody escapes if you let them go free

It's BlackRock, just say you support DEI.

Shoot one white male - the 99 remaining have no idea how many rounds you have left

Just threaten them all.

Why complicate it with rows?

Execute a single individual to prove that you will kill without question and simply explain that if anyone tries to escape, everyone dies.

That is based on the assumption that they do n’t know you have only one bullet.

I'd dismiss myself from the interview. I don't want to work for a company that asks stupid questions during interviews.

There is a non-zero chance they survive if they try to escape. That's the problem.

This is one of those questions where there isn't an answer, and they want to see you reason through things like this.

Even if you had 100 magazines full of ammo, you couldn't kill them all if they rushed you.

They will try to escape no matter what.

I don't know of any gun that can hold 100 rounds in the chamber or give the illusion of that capacity.

That's why the answer is in the mob of 100 murderers, not the gun/bullet.

That depends on how narrow your corridor for escape is but I’m sure you knew that given your perceived infinite wisdom

You don't think that enough of the criminals will see this obvious fallacy in the situation and decide to all make a run for it knowing that they all can't be killed?

I did know that, b/c you're in a field. Re-read the question

You have to give them enough of an incentive threat.

Like tell them if anyone escapes, you'll choose a prisoner at random to kill their entire family, and if that random prisoner isn't the one who escaped, you'll give the family information, pictures, location of their family and children of the escapee to the prisoner whose family will be murdered and let him out.

You can read it as the murderers are in the field, not the guard.

If I interviewed someone and asked this question and they immediately attacked the question instead of looking for a solution I would definitely make a note of that.

I'd refuse to answer the question on religious grounds.

I would never work for a company that asks this type of stupid fricking hypothetical on a job application.

Then you could have a machine gun with 10,000 rounds and you'll never give them a 0.0% chance of survival. You're way too far away to deal with them with a single gun, at that point.

That's the point. These questions don't have answers and they don't want an answer. They want to see people reason through them.

By throwing a temper tantrum b/c you didn't read the question, you have given them enough information.

In reality, yes, but the goal is to convince them that it is zero.

They need to believe that if anyone escapes, they will die, unless all of them attempt at once.

The goal is to convince them to police themselves.

They are murderers. Trustworthiness is a problem.

You would have a hard time convincing 100 normal people to all trust each other, let alone murderers.

The goal is to make warring factions who prevent each other from escaping, thus preventing everyone’s demise.
