When you are browsing profiles in the Meet section, here is how you get the most out of your search:  

1. Swipe left = You are passing on that profile
 2. Swipe right = You are interested in the profile. After you swipe right a notification will be sent to their profile. If they swipe right on you, you'll receive a notification that you matched and will be able to chat.
3. Want to see more information about them? Tap the "^" arrow on the bottom, right hand corner of their main profile image. This will expand the person's profile so you can see their identity, friends, fun facts and more. You can swipe right/left from this view as well.
To exit the view just swipe down or tap the arrow to go back to Meet view.
