So I have been admitted to my first choice grad program in physics. However, I am worried about job security after my PhD, and was thinking of staying an extra semester or year at my undergrad institution to pick up a double major in CS. I already have 3/4 of the major (via applied maths courses), so it should be easy to do in a year.
Is this a wise choice? Will my grad school frown upon it? I'll take some physics in the meantime of course. Money isn't an issue.
Thanks!
In addition to taking into consideration what Vanadium said...
This is something I cam completely sympathize with as I was in the same boat( slightly different) as you just two weeks ago. However, I was choosing between a job offer/deferring versus starting grad school Fall 2015.
Make a pro/con list. Think about your long term goals/career goals. For me: I do not want go into academia, however I also really wanted a physics PhD ( I love physics and I want the option to pursue a research oriented career in the industry).
Think about the type of skills you need for the types of jobs you are interested in. You can pick up programming, data mining, machine learning etc from PhD physics programs as well, but that all depends on you and the type of research you are interested in.
There are going to be some companies that specifically ask for CS major , but there are also companies that take into considerations natural science majors provided you have the skills they are looking for.
From my experience during interviews and even the job application process: Make sure you have the skills they are looking for ( even if it's the minimum requirement), demonstrate that you like to learn, that you are independent as well as a team player, and that you can communicate. Communication is key to get past HR. It's what you communicate in your resume/cover letter or from networking that gets your foot in the door.
(No point in listing technical skills because it depends on type of job).
Having read the above, ask yourself why you want to go to graduate school for physics? If you have NO idea what you want to do with your life, grad school is not the answer ( but defer, if you can, so you have the option).
Edit: I want to emphasize that skills you learn during Physics PhD will be more important when you are on the job hunt outside of academia. You have to know how to market those skills, however. Maybe someone with a CS degree can give your tips too. The economy is something to take into consideration too, but who can predict what happens in 7 years?
