I was contacted via their recruiters at SR2 (that profusely reassured me they pride themselves on giving good feedback, and that I was a good match for the position). I had the first interview (Zoom) which lasted just over 1 hour. It was an informal relaxed interview, with some technical discussion, which I enjoyed. Unfortunately, I never heard anything back. After the recruiter finally answered my calls, I was told they couldn't provide me any feedback, and was told Tumelo wasn't providing any... so ghosted.
