Sanctuary AI Machine Learning Operations Engineer interview questions

Had a recruiter screening, hiring manager interview and systems design interview. On the third interview I was told on the day that there had been a mix up and I was doing a system design interview instead of a coding interview, they offered to let me reschedule, but I went ahead with it. After two weeks I got an email from the two recruiters I was dealing with telling me they were figuring out their list of finalist candidates for the role. After that, both of them ghosted me despite multiple attempts on my part to reach out. The hiring manager also ghosted me despite us previously chatting on Linkedin. Pretty disappointing behaviour
