Do companies offer jobs to college grads?

So this came in my mind. So right now I am in coop Feb-April. I can defer by Monday.

I was speaking with my dad he said if you defer now, you will miss the opportunity of companies offering jobs to college graduates because I will have to do the coop after my last semester. Meaning companies come to college and hire grads.

I also spoke with my brother and he said it depends on the college and the program. (I am in Mechanical Engineering)

Technically, I will be graduating 4 months late, but during that 4 months I will be getting paid.

Right now I am in coop with my dads company with no pay.
