I was only trying to learn it because a take home coding assignment for an interview asked to use maven for its build process. I found the whole experience (using maven) disheartening while I was able to code up the assignment using maven and my inexperience with it cost me going to the second round. I have only myself to blame though.

That sucks :(. But I can tell you there are plenty of organisations (e.g. Thoughtworks) where Maven is regarded as a bad tool that should be avoided. That doesn't help you much if it's part of a job you want, though. :(
