According to the HR manager, they were hiring for three positions. I spent well over 8 hours doing the coding challenges, included unit tests, and even went beyond what they asked for.
After the final interview, I was informed that another candidate was selected, even though they had three positions. The Hr person left it very opened ended saying I was an excellent candidate, and that I could still be in the running just like the other person that reviewed on here.
as far as the coding challenges, by now you should be able to search on github for angular-github-issues and find the trivial coding challenge, along with the backed java portion.
