1) Try to make your internship with a company do not look an academic ritual as is the case with most MBA's. Make it speak something about you and the project you have undertaken so as to induce the employer to offer a chance to you.
2) Try to net-work with right people like your college alumni who are currently employed or by joining professional clubs where you happen to meet professionals so that they can refer you when there is an opportunity.. It is said , ordinary people work, smart people network.
3)Try to acquire some extra skills relavant to your career by doing short certification programmes beacuse when all are equal, some are more equal.
4)Try to garb the first opportunity even if the estblishment is small and package not attractive as it is necessary to have biginning. The key is to earn your fist penny and the pounds will take care of themselves.Many MBA's may not rightly use thier discretion and look for a flashy start and loose an opportunity to make a beginning.
5) Prepare well for the interview in respect of your subject and summer project/internship etc.
Trust the above suggestions may improve chances of your selection. All the best.
