Workday Software Engineer(Internship) interview questions

Got an on-campus technical interview after a career/internship fair the following week. Then, a 1-hr behavioral phone interview the week after this interview, mainly teamwork based questions. However, I had to wait 5 weeks after my final interview before the rejection, and the recruiter was completely unresponsive to my follow-up emails.

They went straight into UML-like diagram problem solving. It was purely a technical interview. I was surprised for my first interview that they didn't ask me anything about my background or resume.
