Research Robinhood as much as you can before your interview so that you can discuss the specific languages they work with. The need for programming knowledge (and which languages, in particular) will depend on the role to which you're applying. Some roles may not require any previous experience in coding, while others will require at least a rudimentary working knowledge.

"I've worked with a broad range of programming languages through various professional and academic projects. I consider myself fluent in C, Python, and PHP. In my current role, I work primarily with C, but I pride myself on my ability and passion for learning new programming languages and would be able to do so, if hired, for this role with Robinhood."

"During my training to be an engineer, as well as in my current role since graduating, a majority of my experience falls within Python. My current role delves deeply into artificial intelligence, and Python is awesome with this advanced technology. As I understand it from talking to an engineer here at Robinhood, it would be helpful to learn Django for this role. Though I haven't worked directly with Django, I believe my experience and willingness to learn would have me up and running in no time if hired for this role."
