I applied online. A recruiter reached out to me asked for a time to talk, and I received a Zoom invitation for the next week. I entered the Zoom room and no one was there. After 10 minutes I followed up with an email asking if I had received the wrong link. No response. After another 10 or so minutes I left the Zoom. A few days later I received an email inviting me to speak with the hiring team, from the same recruiter, and again asked for a time for a call. No mention of the previously missed meeting. This time I responded that I was no longer interested in this position, due to being stood up for our previous call and no communication. The reply was sent to the email in the reply-to, and I immediately received a response that the group only accepts emails from people within the organization or from its allowed senders list, which I am not on. If I had actually wanted to give them another chance, not sure how I would've. I'm marking this interview as "Very Difficult" because it's very difficult to have an interview when they don't show up or respond.
