Taskize Site Reliability Engineer interview questions

After interviewing with the company for 3 weeks AND completing a final interview they proceeded to not respond with any sort of feedback even when I requested it from the Head of Operations Engineering at the company. One would assume that after putting in time and effort to complete the interview process, the company would have the decency to provide feedback. This is the height of unprofessionalism so beware that when you interview at this company - they don't have a focus on people or culture. They didn't ask a single culture-fit question either. The interview process took place in 3 rounds, the first round was an initial 30 minute call to introduce the company and the role and ask a few questions. The second round was a technical test, it was based around installing and setting up applications on a server. The third round was an hour long technical interview where they asked me to draw out the architecture of a solution and describe how it works and then some standard technical questions.
