LOR from non-faculty OK?

<p>I'm applying to masters programs in computer science, and I know several schools ask for, or state that they prefer, letters from faculty and people you have done research with. Well I'm pursuing my degree to work in industry, not to research in academia. I also feel like that's fairly common for a computer science masters, since it's such a practical field. Do you think it's ok, then, to get a letter of recommendation from a supervisor as opposed to a third professor? </p>

<p>I haven't done any research, and my bachelors degree is in math so I don't have a lot of CS options. I'm already using a math professor for one of my LOR's. If I need to get a third, then I'd be forced to go with another math one. Meanwhile, I had an internship where I programmed a search engine for a private equity firm, and I feel like a LOR from my supervisor would be much more useful to an admissions committee than any math letter.</p>

<p>I am in the same situation - undergrad in maths, two letters from math prof (which I know well) and the 3rd from a CS prof (whos I’m not too close with).</p>

<p>I think it will probably also depend on your field of interest in CS. For example, if you are interested in theory then a Maths background may help as much as a CS background.</p>

<p>i think that will be OK.</p>
