-Minimum backlogs are preferred - I think a few tech companies visits the campus every year, idk about the details about them as I'm currently on my 5th sem -I think my senior friend got placed for a job that pays around 20-25k - almost all graduates from an engineering college gets a salary around these figures, so don't worry

Placement officers along with collaborations from companies occur every year. The placement officer is very helpful and if you're not that bad in your studies then they will help you get into a good company with a good package. Training sessions and classes are also provided for free and company visits are also provided from the college.
