Thanks! Here's a secret, they don't actually care if you have a CS degree or 5 years experience. You can ignore that on any job description. If you can prove that you are able to do the job, that's what they are looking for.

Another quick point, those CS concepts will come with practice, and you might not know every aspect of what is happening in the CPU when you use .sort! on an array, but I assure you that you will not be required to rewrite sorting algorithms in any job you should be applying for.
