How does GitHub relate to current IT jobs?

An MCA can open routes into software development, testing, databases, analytics, networking, cybersecurity and other IT functions. Employers will still look at practical skills and experience. If your target role involves GitHub, include at least one demonstrable project rather than mentioning the topic only as a skill. This point is specifically relevant to the GitHub aspect of MCA study. For this specific question about GitHub, the practical takeaway is to relate the concept to your own MCA learning goal.
