This question already has an answer here:
I am applying for a few researcher positions that don't specifically require programming skills (i.e., they don't have programming skills listed in the job postings), but based on the job descriptions, having some will definitely help given the nature of the job responsibilities.
I am not a programmer, so I definitely don't want to embellish or exaggerate my level of proficiency in my resume. But I have written scripts in Python and C++ for data cleaning and processing before data analysis in my PhD research. The datasets I've had to deal with are considered big in my field, but, unfortunately, not considered big in other fields (a couple of gigabytes). And for my research, I have also used C++ to code a bunch of iterative statistical procedures that were originally coded in a different language for speed improvement. So in a sense, I am comfortable with using both languages to tackle specific tasks.
So my question is, how should I describe my level of knowledge in my case. Is "familiarity" or "working knowledge" an accurate description? Thanks!
