M.S

General requirement for ms is 6.5 or above in IELTS + your bachelor's marks and GMAT/GRE score.

Try to get good job, which is possible. If you're planning for further studies then MS would do good to you as you have already done M.Tech. Doing MS will make you technically more sound. You can also try for P.hd. program if you find yourself comfortable for it. So you should first decide that whether you want to get a job or go for further studies. Always remember getting more degrees is always good.
Hope it helps.
