"(づ◔ヮ◔)づᕦ(´•ヮ•`ᕦ)" is a combination of two emotes, the first one representing a person giving a hug and the second one representing flexing or showing strength. It doesn't have a specific meaning but can be used to express excitement or enthusiasm. "It was a nice meeting" emote is not a commonly used emote and does not have a standard representation. However, it could potentially be represented by an emote such as :) or 😊 to convey a positive sentiment about a meeting.
