First, there was a coding challenge on the platform at a LeetCode medium level. I completed it and was invited to the next step: an HR screening. The screening mostly repeated what I had already listed on my CV. Then I received a link to the next challenge — a home assessment task in Ember. When I first heard that, I couldn’t believe it, but it turned out not to be that bad because they didn’t ask me to build an application from scratch in Ember; I only had to fix some bugs in an existing application. They provided a fairly detailed README with the requirements, and they even discouraged candidates from asking follow-up questions. I built the application according to my understanding of the requirements and checked that I met each one. Nevertheless, I was rejected with a one-line feedback stating that my application didn’t meet the requirements (without any details). When I politely asked the HR representative for more specific feedback, I received a generic reply saying they appreciated the request and would pass it on to the Director of Engineering. No one ever responded to my follow-up. TL;DR I spent 3 hours for them; and they answered with one line.
