If you graduated from a top-tier college in your field of study and have excellent niche technical and professional skills, your market value rises. In this case, if you have a job offer that meets your short- and long-term career goals and you're happy with the remuneration, challenges, and learning environment, you should consider accepting it and postponing your MBA by a year or so. A few years of professional experience will undoubtedly boost your CV and qualify you for top-tier B-schools in India and abroad.
Alternatively, if you don't already have a satisfying job offer or want to pursue your master's degree for other reasons, IIM Rohtak is a good option.
If you don't have a job offer and only want to pursue an MBA from a top-tier MBA program, this is a difficult decision to make. Firstly, wasting a year in preparation is not worth it. You may believe that with a high score, you will be able to pass the exam next year and gain admission to top B-schools, but the truth is that even MBA colleges frown upon a gap year in their admission interviews, and it is difficult to account for when interviewing for placements and jobs.
Go for IIM Rohtak and make the most of the opportunities there. In reality, it is a central government-sponsored institution with standard and excellent academics, curriculum, and campus infrastructure.
