In general I recommend bringing up shorter workweek after you have a job offer. At that point they've reached point of "oh this person is quite good" and they've committed in their head. Still will be lots of companies that will say no, of course, so it's a numbers game, best done while still employed (ideally at a company that already gave you a shorter workweek). And, yes, some people translate commitment to "we want you to work 24/7". You probably don't want to work for those people even if you're looking for regular full time job.
