IGNOU is recognised by AICTE and is run by the central government. So if you are looking for a government job then it’s not an issue. Also, IGNOU is better than many small universities like SMU (Sikkim Manipal University).

IGNOU is the best option if you are tight on budget or you prefer learning while earning. 

MNCs prefer a formal education of 15 years. For additional education, you can go for IGNOU. But if your Bachelor's Degree is also from IGNOU then this might be a problem at the time of employment.

It’s important to note that at the time of employment regular colleges are always given more preference than distance education. So it’s recommended you pursue MBA from a regular college. Let IGNOU be the last choice under special circumstances such as a tight budget or preferring distance learning due to personal reasons.
