What would be a good double major with Computer Science?

I like the suggestion of a business degree. This is one that would serve you well in any company you end up working in. But my first reaction is to choose an engineering discipline. Something I've always found invaluable in my work in computer science is the ability to understand and work with and design the machines that they control. It's also helped me gain most of my patents in that many complete solutions require not only the algorithms that control them, but knowledge of the behavior of the physical world that it interacts with.

The same concept applies to any industry you end up working with. If your computer science background gets you a job in a medical industry, knowledge of that would be invaluable. Every business that straddles multiple other areas benefits greatly from personnel that can communicate across those areas.

As I often do, I'll recommend you take a Personality Assessment Survey test, like RIASEC This test is a set of questions that will match your personality to those of folks in a variety of careers who have been successful and happy. This help you target the other areas that you would be happy working in and a good way to choose a second major efficiently. And find out other jobs you would be happy doing.

No wrong answers here. A lot depends on your future aspirations. Kudos to you because I was too bogged down in business classes in undergrad to consider a double major.

I will weigh in on a business degree as a second major in general. Each department in a business does not operate in a vacuum. The more you understand how your role in Computer Science fits the entire business engine, the more opportunities to move up in cross-functional and higher level managerial roles. (if that becomes your desire). We get many computer science undergrads who come back for an MBA when they are ready for upper management, so if you choose something other than business as a double major, you can always go back for an MBA when the time is right.

With that said, why not double major in something you have a passion for? Comp Science is a solid, marketable degree, which gives you have the leeway to go with something totally unrelated. What do you like? Languages? (good for possible international assignments). Political Science? Film/Cinema? English/writing? You name it, you really can't go wrong. It makes you a more well-rounded person and most likely a fascinating conversationalist in social situations. Undergrad is still a great venue to experiment and take risks. Grad school is when you really have to get specific.

All the best to you. I hope this helps.

I would personally recommend perhaps business as a second degree. There are a large number of companies that have great need for both computer skills but someone who also understands how businesses operate. Having this understanding would open up your career options in long run especially in the high level analyst positions which pay more in the long run that a typically programmer position. Best of luck.

I would actually vote comp sci and then more comp sci (go for master's classes if you have extra time). I have three separate undergraduate degrees, and it didn't help at all. I could have done a master's in less time, and been farther ahead :\

But, if you want to focus on some specific area for employment, branching out could help (bio/chem, finance, whatever).
