Process
Applied online and received an invitation to a 75-minute HackerRank online assessment with two questions.
This was followed by a very general HR phone screen.
Next, there was a CodePair on HackerRank with an engineer.
Their application management system has some issues.
I was receiving emails sometimes to an old email address and other times to my current email. I informed them of this, but they still sent emails to the wrong one.
When on the phone, they use some sort of headset and/or software, and the sound quality is not good. It's definitely worse than a normal phone call.
Questions
Online assessment: Perform a given distribution algorithm on tabular numerical data.
Find the "best" subtree. (This question uses misleading terminology of flows and cuts, but it has nothing to do with flow networks nor max-flow min-cut).
Codepair: Explain hashmap, process and thread, and a question that is essentially random sampling without replacement.
