Huge Android Software Developer interview questions

I was asked to complete a take home currency conversion application as an initial programming test. I finished the application and turned it in, only to receive this email two weeks after.. "Apologies for the delay. We have put things on hold for the time being with our Android search, but will be sure to reach out when things resume. Thanks" Pretty disappointing that I spent the time to write out a full functioning application to not even be assessed / considered. Guess we will see if they ever reach out!
