GitLab Production Engineer interview questions

Very long pre-screening process: first task of answering 7 Long questions that easily take 5-10 hours, then another bigger challenge on a hybrid software & infrastructure design which also takes at least 10 hours to submit several pages of design,diagrams,specs, justifications. They do examine technical ability from multiple angles which I found great, however the next step was... An awkward screening process by another internal "global" recruiter. The arranged call was a no-show that was covered by the recruiter's colleague a few minutes after the scheduled time, rescheduling it some days later. The worst thing was the 15 minute silence and unresponsiveness when I joined the call, listening to mumbling and heavy coughing while the recruiter was totally unresponsive to my questions, lacking any sense of leading the interview and introduction or anything typical that is expected from an HR interview. When the recruiter became responsive, she was unnecessarily aggressive, non-communicative, intimidating, of course non-technical, seemingly unaware of the pre-screening tasks and any kind of performance on them. Asking and pressing on the wrong questions like she just read the CV, making you really wonder whether she understands anything about your profile or the information that a recruiter needs to extract to properly screen a candidate's strengths, ability to fully work remotely, understanding of Gitlab and Gitlab's business and infrastructure, friendliness, soft skills et cetera. A few days later I receive a rejection with a diplomatic answer that the decision was joint between infrastructure lead and the recruiter.
