To decide between IIM Ranchi's PGDM HR program and the Great Lakes PGPM program, consider the following questions:
If your answer to the first question is "Yes" and your answer to the second question is "No," you should consider IIM Ranchi's PGDM HR program. If your answer to the first question is "No" and your answer to the second question is "Yes," you should consider Great Lakes PGPM.
If both answers are "Yes," you should reconsider whether you really want to change careers after 3 years of work experience. If you still want to pursue HR, IIM Ranchi's PGDM HR program would be a good option. If both answers are "No," you should consider Great Lakes PGPM, as it has a better return on investment due to its shorter duration.
