The placements at Delhi University have a dark side that nobody tells you about. This is because you can experience it only if you yourself are in one of the mediocre colleges of DU.
For the best colleges in North and South Campus or Off Campus (SRCC, KMC, Miranda, Hindu, Venky, SBSC, Gargi, LSR, SSCBS, KVM), placements are not a big deal. This is because they will get you into big MNCs with high packages. Your performance in the interview is also significant.
But here is the dark side. If your college is mediocre and not among the top colleges of DU you will get placements in MNCs but for trivial positions like Customer Service Executives, Process Associates, or Airlines with Cabin Crew. The packages here are as low as 1.5-3.5 LPA.
So it all really depends on which college you are in.
Placements at Delhi University will vary from college to college and nobody will have an actual idea while applying for colleges with high cut-offs.
You must study well and score a good score in exams. It will help you in applying for in-office internships and gaining work experience.
