CO2 AI interview questions

I had a meeting scheduled at 12:30 PM for the Full Stack Software Engineer role. I waited until nearly 1 PM, yet no one showed up, nor did I receive any notice of cancellation or rescheduling. This is not the first time I’ve encountered scheduling issues with CO2 AI. In a previous process, my interview was postponed multiple times with little communication or consideration. when i addressed my concerns, they simply replied "if you no longer want to keep the meeting I'm happy to cancel it" no professionalism of this recruitment process. The least thing I expect is clear and respectful communication
