SentinelOne interview questions

The interview process was completely unprofessional. The scheduled technical interview was canceled a day in advance due to vacations, but a new date was promised. After that, there was no communication for 10 days, and only after I inquired did I find out that all the positions had already been filled with candidates who did not advance to the next round in some previous stages. However, all the filled positions are still advertised on the website.
