Unlike others relying, I think your interview question is good. Let's break down why.

In your phrasing you asked "what happens". Did any candidates you thought were good give the actual answer: a disaster for Libya, and the person is removed from power?

That is the actual answer.

Of course not. All of your "passing" answers to "what happens" includes building up infrastructure, basic services, etc.

In other words, what you really just asked didn't match your words. You really asked: "Convince me that you are qualified to lead Libya".

Unsurprisingly, the people who realized that this is what the question was, and gave you an objectively false answer, get a passing grade. Those who did not this, or who answered correctly as asked, fail.

Those who were understood what you really wanted, and who also successfully convinced you that they're qualified to lead Libya, "built great sustainable orgs" whereas "whose who did poorly where usually shown the door within a year".

You could have done just as well asking "The company has decided we are building a social network to compete with Facebook. We put you in charge. What happens?"

What actually happens of course is nothing good. It doesn't mean it's not a bad interview question, but a good answer is not the factually correct answer.

Without knowing what kind of company you're working at, here's the way I'd answer the "the company has decided to pivot to building Facebook. You're in charge. What happens?" first based on what I'd actually tell you, then truthfully.

Answer you want to hear:

"Boy, agrippanux, this is a tough one. I hope I'd get some equity because as you know, social networks have a network effect where success means they blow big, and that's what we're going to do. agrippanux, I've long been interested in social networks so even though your company is not really in this space, I think I could really identify some of the areas people feel strongly about, including advertising, privacy, filter bubbles, and also social media addiction. We will end up having to tackle the network effect, so we will start by identifying niches where our company already has a really strong presence. agrippanux, we don't really do much direct technical support to customer's issues, so I would start by having our web page redirect seamlessly to our in-house Facebook competition that I'm building with the team you give me, as a kind of closed beta, so that we can get a steady stream of users asking us questions and getting used to the network. We can then stealthily work on the underlying technology, while testing it with a continuous stream of real user input. As a next step, we would license this answer solution to other companies. Companies will appreciate being able to have the narrative be on their pages, and by building up factual answers and technical support, we would end up building up an expectation of value and reliability - the opposite of "fake news" plaguing social media. Many early adopters are avid supports as well, and the next step will be allowing some members to answer other people's questions as well. The third stage will be introducing some company events such as pizza parties and this type of thing, in the biggest cities. This kind of approach will let companies capture their own audiences, promote those who support their products as online grassroots supporters, and be a clear alternative to the marketing mess on Facebook. Over time we are a viable social network built on the technical foundation that you have, agrippanux, in this very building at this very moment, and based on the good will and brand that your company has spent years building - and leverage that to be a successful full social network. That's why you've put me in charge of replicating a social network using our technologies and employees, and I am confident we can do it." (Then, after a beat, since your jaw just hit the floor at how awesome my answer was.) "Hey so do I get some equity if I help you take down Facebook or what?"

That's a great answer. It's not truthful though. Bam. I just got hired for whatever role you're actually interviewing me for.

Truthful answer:

"Whoever made this change in direction is an idiot. While it is nice for me to get the resources to roll out a social network 'to compete with Facebook', it's probably doomed to failure, and my top priority would be getting out of it alive. I'd probably spend a lot of marketing money getting a few million transient users who aren't actually engaged, and then jump ship to an actual social media company that knows what they're doing and has a mature product with a real value proposition. This company has no chance of creating a viable social network."

See? One of them is the truthful answer that ACTUALLY describes what really happens. Just as you asked. It's similar to exec consolidating power and crushing opposition. And one of them is the fake answer that answers the real question: "Convince me you're qualified to replicate Facebook under our company, using a few hundred thousand dollars." It's similar to the question "Convince me you're qualified to lead Libya."

An insane question. But perhaps a good question.
