After a brief (~1/2 hr) phone interview, I was invited to an on-site interview which lasted around 4 hours.

I feel that I did well in the interview and I got a good response from those interviewing me, the manager I talked to at the end of the interview, and from the HR department afterwards.

Despite the positive response, I was told that since I had already graduated, I didn't qualify for an internship. There were also no current open entry-level Software Engineer positions at the branch.

Hopefully I can find a spot in the future, as Workiva seemed like a pretty neat environment to work in!

Something along the lines of, "Describe the data structures that you would use to build a book tracking system for a library." This involved using a whiteboard to sketch out data structures and answering questions on how I would implement various tasks (lookup by author, title, etc.).
