Sadly, Job bank has been very disappointing until now (at least for me). I am a Devop working here in Canada, and my current job is likely close to Software Engineer's NOC, so I chose that and was expecting to find some jobs with LMIA through Job Bank. To my surprise the suggestions that I received were nothing even close to Software / Computers / Technical side, some of them were pretty interesting suggestions "Sous Chef", "Janitorial Supervisor", "Librarian", "some store Manager", "Barista" etc.
I'd say it would be better to come here and find a job or arrange for something else, may be ask a friend / family member living in Canada who can help you with job prospects. There might be some genuine recruiters who can hire you if you are ready to get your PR on your own. Again all this might depend on what NOC you are applying for, what are the job prospects for it, how is the labor market for it and so on.
