Good luck.

You are advised to prepare and appear for CAT so that even if you do not get admission in IIM, you may get admission in other top B-Schools which use CAT score.

You can get jetking books. Those are best. Attend online exams as much as possible.

IIMs give 75 percent to 65 percent preference for CAT score and 25 to 35 percent for personal attributes such as academic record, GD and PI, personal achievement and other factors please be informed. His question is about job, not about IIM selection

Yes, there are some top companies which consider a candidate who has scored at least 60 throughout his academic life. However, there might also be some companies which do not consider these academic scores (or give less weight) and give more importance to the overall performance during your MBA journey. So, you have decent chances in such companies.

Hello Hiren,
It's impossible to predict that as of now. See, it entirely depends on the company whether there is any vacancy in your choice of city. If there is, they might post you there. But if not, then you have to work somewhere else.

IIMs are top notch institutions when it comes to MBA. Other than those, there are various other institutions like FMS-Delhi, XLRI, JBIMS, MDI-Gurgaon, ISB-Hyderabad, Symbiosis, IRMA, etc.
