I can say this for CAM — they have a policy of never allocating you to the same partner who ultimately put in your recommendation for the internship. As a result, unless said partner informs the the partner you're actually assigned to, no one in your team knows about how you came there.
(Though realistically CAM HR policy is notoriously well-known for being much more concerned about which college you're from your GPA that if you come from a lesser-known/T3-or-below college, they'll probably know that you're there through contacts.)
Regardless, in terms of actually answering your question: if you do your work well, your partner will recommend you through feedback, which, after a basic HR scrutiny regarding your year, grades etc, will get converted into a PPO (if you're from GNLU or above) or a callback (if you're from a lower-ranked college and the feedback was less than extraordinary). That's it.
So, tldr; how you got your internship stops mattering the minute you start making your seniors' lives easier.
I'm in final year (about to graduate in July) with not much hope from my college (lower tier NLU). I've got an assessment internship opportunity (3 months) at a boutique firm but their pay is very low and I'm also getting an internship at KCO (not assessment) through contacts. Which one I should go for? Are there any chances for me to get in?
