This is actually true, nothing smug about it. It's an internship, and a lot of companies look for people who might be interested in working for the company after school's over. If someone has that much to think about that they would need more time, then they clearly have no interest in the company itself- they're just looking to get the most money, regardless of who it's coming from.

The differences in compensation aren't that huge, and it's just a summer, and the interns themselves are usually still living off of their parents. So, usually anyone that's agonizing over nickel and dime stuff that early in their career likely has no enthusiasm for what they would be working on (which by itself is reason enough for not taking an intern), and might be super entitled on top of that, also not a good thing. Because, again, we're talking about mostly CS undergrads here. A very small number of them might have a big impact over the course of a summer, but for the majority of them it is practically charity for these companies to take them on- they're not getting anything out of it other than giving a potential future employee some hand-on experience.

And, it's an employer's market- there are plenty of equally qualified interns to choose from in many cases, as well as a small window of time in which they either have to pick an intern or not get one at all. If they gave everyone weeks to make a decision, they could easily end up taking so long to even find an intern that they would run out of time in which to do it.

There's a difference between being enthusiastic about working for a company and being so keen to work to them that you're not even going to consider alternate offers. But seriously, you think that someone is going to be a bad employee just because your company isn't their one true love in the world?

I don't really think there's a justification for exploding offers that prevent people from considering alternatives, it's mainly just a way for employers to attempt to get the upper hand. From what I've seen it's often a) arrogant employers who can't comprehend that they're not the only attractive place to work b) game-playing employers who know that most college-age people aren't going to stand up to unreasonable demands and that these sort of gambits can prevent them from having to actually compete directly with other employers c) employers who do have an urgent need to fill a position (i.e. who aren't hiring an intern).

That's simply not true. CS internships vary widely in compensation and often approach entry level wages. I know interns making 7500 a month at Palantir, 4800 at Intel, 6500 at Amazon,and others. All of them have different relocation, housing, and other benefits on top of salary. None of these interns are from where they are interning, they all are flying out to live in a different state off of their own dime. Some of them even had to fly in to interview (as a freaken intern!). The CS job market is weird right now.

Actually, the differences in compensation can be much more substantial than one might think. I spoke to a few interns last year who were entering the job market, and compensation ranged from fully paid housing and nearly 100K (annualized) to numbers less than half that in the same geography. For college students, the difference between earning 10K or 20K in a summer is likely a decision that could require more than a weekend if the 10K comes with external upside.
