After reading about the negative attitudes of Cloudflare recruiters on Glassdoor, I had a similar experience. I had an initial discussion with the Hiring Manager and was told I had to go through a HackerRank online test. However, in line with the typical Cloudflare recruitment attitude, I never received an email for the HackerRank test, nor any further response. It was my fault for proceeding with the interview process even after reading so many negative reviews about the company culture and hiring attitude.

Simply blacklist such companies with bad attitudes. My time was wasted, as I already have interviews lined up with many companies, including FAANGs.

Nothing was asked of me.
