I'm currently a back office developer at an investment bank in New York, with about 3 years of full-time work experience. I don't have any experience with C++, would taking both of the quantnet courses help me transition to a quant dev or C++ dev job? I have some doubts because I don't see how I can convince people that even though I don't have professional experience with C++ I've learned the language through two online courses and that they should hire me.
