Lots of networking events are focused on sales or marketing, they attract lots of people looking for work or looking to switch jobs. Often times they are not advertised as 'networking events' specifically, but if the primary point of being there is to meet other people then it is a networking event. Even if there is some guest speaker or something, you will be able to tell why everyone is there.

User group meetings are the flip side of that, while some people are there to meet others, most come to learn something and their motives pivots around that point.

People who are looking for jobs or work, are rarely you ally in finding more work for yourself.
