Quantcast Software Engineer New Grad interview questions

First received a hacker rank code challenge, which I had 48 hours to complete, and got all test cases working. The question was "Query by Example." Next, I had a screen with the recruiter, who informed me there would be two technical phone screens and then an onsite. I apparently didn't pass the technical phone screen.

They scheduled a Coding Challenge for 48 hours. The recruiter said I can take as much time as needed, it will not affect the decision. But I heard from another friend that another recruiter asked them to finish within 3 hours.
