This was the initial HMgr phone interview. There were questions about my previous experience and other general questions. A lot of emphasis was placed on how my previous experience suits the current job description.

Code a high-level class hierarchy to implement a library system that includes library book checkouts, returns, and search based on title, partial title search, author, ISBN, and other metadata.

There were questions about why I chose a particular data structure and how it can scale in terms of future changes and performance.
