How do the tier 1 firms work for a reference based internship?

Do they get a call back or a PPO?

(Most of the interns are referred so these firms consider merit?) Even if the do consider merit then the NLU thing comes up.)

What should a Non-NLU student do???
Dude, it doesnโ€™t matter how you get in, once you are in focus in giving out your best. If you do a good job youโ€™ll get a callback most of the times irrespective of the status of your college n other things
