Your speculation and projections are not accurate. Again, my strong advice for anyone considering NU is to join NU forums.
From the posts of the NU parents I have read in this forum, I think they have a firm understanding that personal initiative is required for any type of job and there are no guarantees. The co-ops themselves are not guaranteed and just like in any type of job, the offer may be rescinded if the employer needs to cut back, and students need to pivot. It’s a very real-world situation. I can’t say I know any NU parent who thinks their child did not need to “hit the pavement,” including me. My NU graduate did “hit the pavement” to find a job after graduation, however having the co-op experience was instrumental in assisting with the process. There seems to be quite a bit of misunderstanding here, and frankly incorrect projections, about NU students and families. Many times, co-ops do lead to job offers. It is never guaranteed, but it is also not uncommon.
