What should i do after my engineering graduation?

You have options like MBA and M Tech. If you feel you can contribute further to the growing world of technology, then M Tech can be a good choice. But if you are confident of your managerial capabilites, MBA is not a bad choice to climb the corporate ladder. In the mean time you may top yourself up

First : if u r interested in MBA prepare well and give cat/xat/mat/cmat second: u can write Gate exam, clear it and u wud be able to sit for any PUBLIC SECTOR COMPANY( govt. companies, like BHEL, NTPC,ONGC etc )
