Unprofessional. I don't get what really happened. I sent my application and they replied so as we can set-up an interview. We agreed on the day-time and I joined the interview link on time. The HR person from Vonage never got into the call, after 15 minutes I emailed him and after 30 minutes I left the meeting. The guy from HR never got into the interview call and never replied to my email. I also sent him another email the next day but still no response. I'm not sure what really happened but I find this to be unprofessional as they wasted my time. I'm totally dissatisfied with their unprofessional behaviour.
