Site Reliability Engineer Interview Experience - Hong Kong

November 1, 2021

Neutral ExperienceNo Offer

Process

I was given a 72-hour HackerRank assessment. The questions ranged from how to design a distribution service to some MCQs on operating systems.

I believe I gave very good answers. The last two coding questions took me some time, but I accounted for plenty of corner cases.

A day after submitting, I received a rejection. How do you judge a subjective assessment that fast?
