I know these are not revolutionary gender neutral date names but I like them. Alternatively if whoever you're dating just puts "my" in front of a nickname, endearment, or even your actual name it can work in the same way.
If it’s entry to mid level and the interviewer is asking questions that call for an example, use the STAR method (quick google search will go into detail). This helps show you’re a great communicator and can succinctly share info and highlight your experience. Goodluck!
