This is a really helpful post for college graduates looking for tech jobs.

The questions here seemed to be geared more toward applied reasoning and practical values than just knowledge.

The first question could probably be solved if I had been using calculus on a regular basis.

The second question seems theoretical but it is totally plausible and serious question given the drop in facebook stock due to ads. I'm even getting adds on fb messenger. So this is a question of applied reasoning. I like the way you also gave an answer for this one.

The third question also shows how we think and solve a simple problem demanding a creative and analytical answer in a short amount of time.

The fourth question is a value and motivation question and a trick question. It is really a trap. If you say LEARN then how would you like to learn without pay?

The fifth question both applied reasoning and value question. Some of these companies have a direction they are going. If you just calculate the most reasonable way to make a profit you will not get the job. You need to think like them and want what they want.

That's just what I think.

Thanks for asking.
