BigR.io Devops Engineer interview questions

First, I was contacted by a recruiter and given a questionnaire to complete. The questionnaire was extremely thorough, and it took me 4 hours to fill out. After the questionnaire, I went on a call with some people (who weren't even part of the company!) as part of the screening. After all that investment, they said they didn't want to continue with me, which felt like a slap to the face because I had the experience they were looking for and felt like I did well on the questionnaire. Felt like I got "gatekeeped" from a position.
