I can confirm that this site still has pretty much no actual opportunities to find work. At best you'll be subject to receive spam emails to join a survey program and at worst you'll get complete silence from any of the supposed employers referred to in the postings. Does anyone even receive your application? I don't know. I doubt you'll be able to find out either.
I'm editing this after the fact because the whole reason I found GetCADJobs in the first place is because I believe they may be using fake postings on other sites like Indeed to get more traffic Job postings from multiple employers that you cannot find on the employers actual websites redirect from sites like Indeed to GetCADJobs and their postings only have unformatted, copy-pasted verbatim descriptions from Monster.com.
