I participated the first round HR was very nice. I was invited a technical interview for the next stage. But There was no interview because the person, Alex, who is interviewer did not participate. After I sent emails, he replied to arrange another one. Why I need to remind that to him ? As a candidate we are expecting at least an email before the delay, cancellation or postponement. This flippancy about the serious situation angered me. Don't waste your time and energy like these companies.
