AppDirect Senior Java Developer interview questions

First had a phone interview with a senior engineer for about half an hour where I was asked some technologies used in my previous jobs. And then I am assigned an integration project to finish in 10 days. I finished the project based on the requirements even finish some requirements for bonus points and send the source code back to them. No response from the company after 10 days then I sent an email for an update and was told they pass on my candidature. Overall it seemed like they were just following a process - they were not interested in knowing about me or testing my skills. Possibly they had already decided to hire someone else by then. It is perfectly OK if they want to go with some other candidate - but why waste somebody's time like that?
