ZoomInfo Software Engineer interview questions

The process seems disorganized. They rescheduled my on-site because they first told me a day without having all employees in the office (nearly was at my own expense, if I hadn't booked a refundable option). In the on-site, I spoke to 5 people over the course of 2.5 hours. They went through standard data structure questions and a short whiteboard session. They asked me questions about a framework that isn't even listed on my resume. There was also a round delving into my work history and architecture experience. In the time since then, ZoomInfo has not returned my follow-up inquiries, despite them assuring me that I would get an answer within the week. I'm upset that I wasted my time and money traveling to the Boston area, and they can't even say "no thanks".

Bad experience. They wanted someone with more experience, and still invited me, therefore wasted my time. Felt like they didn't even look at my CV before they invited me and didn't respect my time.
