What would I chose SIBM, Pune or IIM UDAIPUR considering IIM brand, growth of new IIMs and covid situation?

Your parameters to judge a college are wrong. You cannot decide a college’s suitability and worth just through these points. You need to look up at what it is offering currently and where it will be standing in the future. Let’s divide this into 2 parts

Short-sighted approach: This includes analyzing the present opportunities offered by the college, its placement reports and the companies it attracts. Most students focus on this only which is not right. It sure is important to look up and compare the opportunities provided by the two colleges. But this cannot be the sole factor in deciding it.

Long-sighted approach: This involves researching and analyzing where the college stands in the future, maybe in 10-15 years. This is especially important in case of IIMs which carry the hierarchy of the older IIMs and have a credibility to climb the ladder. You check the potential of the college because it won’t be just a source to kick start your career but will remain attached to you for the rest of your life.

So what you need to do first is look up at and compare the opportunities offered by the 2 colleges and then see which college has the most potential.
