Online test was multiple choice sometimes it was easy and sometimes it was getting hard. It was average. Assignment was simple problem to assess your ability to implement API . They did not mention any technology or library name. It was free to add and use anything You want and any decision about architecture and implementation as They have mentioned. So I used my experience to implement it using Spring, JPA and I even exposed it as REST API.
