The best way is to crack CAT and apply to one of the IIMs to get the best placements. Admissions to most of the business schools will happen through entrances like CAT, XAT, MAT, IPUCET etc.

A B.Sc. Hospitality degree will obviously lead you to jobs in the Hospitality sector. This degree is more industry-focused. Hence, you may want to pursue an MBA immediately after your B.Sc. or choose to work for at least 3 years prior to embarking on an MBA. Hospitality refers to jobs in Hotels, Airlines etc., You must also understand that people with Hospitality degree and/job experience may have shifted other sector eg.: education. As long as your skills that you have acquired over the years match a certain job requirement, you can work in any sector provided you justify your skills.
Hope this helps. Thanks!

after 10 or 12 education you can join any of the academy which will train u in proper way at one profession. after tat u can join airlines. first you have to decide yourself in which field you want to go. as there are many fields in airline industry. you just go through the Google and find some information about the airlines. u will get detail information about the fields if airlines.
