I was approached through LinkedIn by one of their recruiters. A couple of emails were sent with some information regarding the company, job, and relocation process/package.

A general phone interview followed.

After that, they asked me to complete a technical assessment on HackerRank.

One of the questions I could remember and completed successfully.

1. Identify whether there exists a pair of numbers in an array such that their sum is equal to N

My take-away from all this is that HackerRank is a poor indicator of a developer's problem-solving capabilities. Like so many of these things, it is only really good at assessing one thing: how good the candidate is at completing HackerRank tests.
