@ChrisRussell shared an example of a featured snippet in Google that is in the form of a nicely structured table. That isn't new but I wanted to show you how quickly featured snippets not only come and go for specific sites or queries, but also how they change.
Glenn Gabe is one person I know that tracks featured snippets closer than anyone else I know. He posted the before and after version on Twitter.
For the query [aviation jobs], the featured snippet was originally in bullet format and looked like this (click to enlarge):

And now, for me at least, there is no featured snippet showing up for that query.
Featured snippets also can have images and many other interactive looking features.
