Going through people you know even just asking if they know anyone working in a restaurant who can check if their restaurant is hiring is really the best way. But for what it's worth I thought applying directly through companies would get me jobs the fastest but that didn't work for months until I caved and applied through Indeed and I did actually start getting responses at least and got my job pretty fast. It's a tutoring gig tho so it might be very different in the restaurant industry I'm not sure.
