IBM Entry Level Back End Developer - What are the HackerRank Questions like?

I applied for the entry level backend developer position with IBM (Canada) and they sent me a hackerrank test to complete. The thing is, I have no idea what to expect. Looking through the job posting the description is rather vague. They don't specify what languages are required, just talk about developing APIs, Agile, etc.

Anyone complete this test before? Any insight? Thanks
