How do people get airdrops?

I'm curious, how do individuals typically go about obtaining airdrops in the world of cryptocurrency? Are there specific steps or qualifications that need to be met? I've heard they can be a great way to acquire tokens for free, but I'm not sure where to start or what the process entails. Is it as simple as just having a crypto wallet, or are there more intricate details I should be aware of? Any insight you can provide would be greatly appreciated.
