Codeex Backend Developer interview questions

They called me to invite me to an interview, asked some questions about my English level, availability, etc. At the end of the short call HR said that they would send me some technical task, I said "Ok, Im ready", waited about 10 days or so, but nothing, wrote to their HR, she saw my message but didn't even bother to answer. Never seen such unprofessionalism and incompetent behaviour
