Soon after my application, they sent me a link where I could select an interview appointment from a date&time list. The earliest date was one week ahead. I selected a time slot, and their system acknowledged it. They sent a confimation email immediately. A few days later, they sent me a meeting reminder email, too. I am detailing this organization phase to emphasize that they had plenty of time to organize the interview and to prepare for it. I myself prepared for the interview, by recalling the relevant technical knowledge and soft-skill set of mine, as well as by studying the information available on the internet about the company, about their business and technical solutions. I prepared myself for the interview as professional persons do. At the agreed date and time, I was ready for the video interview, in elegant outfit, as serious people do. A few minutes before the interview (literally, approx. 8 minutes before it), they sent me a two-sentence email in which they cancelled the interview. They wrote that "we have to postpone" the meeting, and that they were going to reach out to me with a new appointment. A last-minute cancellation with this kind of content is impolite and unprofessional. First of all, politeness dictates that some reasoning should have been provided. Even if it would have been a two-word reason, and even if it would have been a fake reason, it would still have been better than nothing. Like 'because of power outage', or 'fire alarm', or 'internet connection issues', or 'unexcepted, urgent business meetings', or anything. Anything. Secondly, if one cancels a meeting right before the start of it, when other participants are already there, then a respectful person would ask the others about the posbbible and suitable alternative appointments. They should have asked appointment proposals from me, instead of writing that they were going to find me with another appointment. After decreasing their own reliability, how do they expect the same trust again? After this disrespectful communication, I was not interested in the position nor in the company anymore.
