Sure, but depending on what you’re doing, “quick” might be years. You can get a PhD in understanding the theory, a PhD in designing fast numerical algorithms, or spend many years becoming a strong software engineer. I think the willingness to learn a diverse set of things is much more important than learning narrow areas fast. The short length of a bachelors usually isn’t enough to get this diversity.
