As noted by ashuindian, the 'easygoing' PNPs of Saskatchewan (SINP), Nova Scotia (NSPNP), and Ontario (OINP) do not require a job offer. Another PNP is that for Manitoba that, while not requiring a job offer, requires some kind of connection to the province. That connection can be in the form of a friend or relative who can show unequivocally that they will assist you with your settlement plan in Manitoba. They do penalize, and seem to go so far as to desire to reject individuals with work experience in another province, on the grounds that you do not have a strong connection to Manitoba.
The sub-categories not requiring job offers within the SINP and NSPNP open up periodically, and each time the intake remains open for a very limited period of time. As of this writing, none of these subcategories is open.
Besides having to wait until they are open, these subcategories are restricted to applicants having experience within a list of NOC codes that are considered in demand in the respective provinces. Nova Scotia refers to them as 'opportunity' occupations while Saskatchewan refers to them as plain old 'in demand'. Most notable is the Nova Scotia includes the popular NOC 2171, the IT 'hub', while Saskatchewan, in the last intake, had just removed this (and other IT-related occupations) from the list.
If you have successfully registered with Express Entry, then you should, with experience in one of the occupations 'in demand' secure enough points to apply to these programs, once they open.
