My opinion: Any learning in a 1-year business program is based on your desire and focus to achieve. No, this isn't from any behavioral science book but a mere fact. I can assertively say that XLRI has good faculty members...but it's up to you to squeeze out the learning...And frankly, 1 year programs are pretty rigorous, so please don't think you can solve for world hunger...be sure of what you want to focus at...As far as job prospects are concerned, in the current scenario, please don't expect that things will be given to you on a platter in any b-school...if you work hard enough and know exactly what kind of job you want post mba, then you'll get it....as long as you are associated with a reputed brand and know the role you want to get into, it'll happen...but the brand alone can't do wonders for you...your past experience is equally relevant, don't think that organizations will hire you just because you've done a 1 year course...even if you land up with a good profile, it's for you to perform and grow/survive in the organization...
So, in short, if you are aware of where you want to be next year, if you think XYZ institute has the desired brand name and can impart the kind of knowledge you're looking for, go for it...
