To become an MRO (Maintenance, Repair, and Operations) after completing a BSc in Computer Science, you typically need to gain relevant experience in IT infrastructure management through internships, entry-level jobs, and potentially pursue additional certifications in network administration, system maintenance, and hardware troubleshooting.

you might also consider a master's degree in a related field like network engineering or system administration. As in computer science it is not easy to get job without masters degree and you should also consider the university which will help you in placement.off campus placement without experience will be hard.so i suggest you to do masters forst.
