I had two interviews, the first one went well, general questions and some technical. But the second interview, which I had spent a whole day to prepare a task for presentation, was the worst interview I have ever had, First, the interviewer came late with no apology, and during the interview due to his awful internet, the interview was interrupted several times, I wasn't sure that I should continue or not; and the worst part was at end when he asked me a question and then got disconnected and never came back, I can't believe that I spent time for such a disrespectful company.
