CloudKitchens Architect interview questions

They found me on LinkedIn and encouraged me to interview. After a preliminary phone interview I was asked to do a second interview, but this time I had to submit a design and do a presentation. I spent about 35 hours on it, and got some feedback to incorporate into the design. I made revisions and interviewed again. It was a massive time sink which I regret. I didn’t realize how much time it would take until I was well into the interview process. A few months later they emailed me to tell me I didn’t get the job.
