IMT GHaziabad is a good institute for management however, if you have job in hand and that job is a role which is in a core sector of your graduation, then I suggest you should go and do job at least for a year. An MBA without work-ex is not a good decision as the second year of MBA is all about those students who have some work ex before.
But if the job you have is not a good job but a BPO/Call center/non-core job then you can consider joining IMT.
Hope this helps. Thank you.
