ZoomInfo Software Engineer interview questions

I applied through College Career Fair then got invited to a day interview on-site. They thoughtfully arranged a pick up truck for us to get us their. The interview started with a presentation about who they are, what they do, and what they have achieved. After that it's pizza and snacks. Then they asked us to write code (Preferably Java) to solve a problem and you will be interviewed independently with a ZoomInfo Engineer who will assess your code and teach you lots of great stuff. If you are lucky enough you will get into a second round which another engineer will interview you by asking you to solve a relatively easier coding problem and complexity. I got a third round by VP Eugenia which is more about your personality, your experience, you future plan like that. I really appreciate their caring for details especially they actually did a lot to make us fell relaxed and easier.
