Both GMC and OMC are equally good medical colleges for internships in terms of the exposure they offer. However, if I had to choose one between the two, I would have opted for GMC.
Students of OMC have to roam around from one hospital to another for completion certificates and waste a lot of time in the process. There are students from all over Hyderabad, and sometimes traveling to the hospital takes 45 minutes. For example, the maternity hospital is at one end while the Psychiatry department is at another. This results in many technical challenges and students might find it difficult to get their degree certificate
So, if you have the choice, go for an internship at Gandhi Medical College because here everything is under one roof so you will bewill be saving a lot of time and effort.
