Excuse me, but if not getting in touch with your colleagues blocks you for the whole day then you probably have the bigger problems than just not getting your questions answered on time:

1. Maybe documentation is scarce, be it code comments or business requirements specs, user stories, epics, etc.

2. Maybe your tasks are ill defined, and you accepted your assignments without asking enough questions upfront...

3. Maybe you don't get enough workload (if you had many tasks to choose from it would be harder to get blocked on all of them)

4. maybe you lack some technical knowledge or other competencies needed to make the decisions yourself instead of asking others.

Lame question: what exactly is HackerRank? Some poor man's version of TopCoder?
