CHECK24 PHP Fullstack Developer interview questions

The process took about 1 month. HR call, online coding, technical interview. We agreed on a date for the last stage of the interview. They was told that there would be another short interview for an hour. A few days later they said that there would be another online coding for 6 hours (in fact the whole day), and then a call. Two days before the agreed date, I asked to confirm that everything would be as agreed, but the company employees began to ignore me, and I never received a response from Check24. Don't waste your time on this company.
