2K Czech UX-UI Designer interview questions

After applying I immediately got proposition about tech interview and time slot. I have confirmed timing and accepted invite with 3 interviewers . But our call was not conducted. I just waited all time at zoom room meantime checking an email. I wrote to recuiter who sent me invite with whom chatted before. I described all this situation, maybe they have any updates or some extraordinary situation. But I've not got anny response.
