ServiceNow Technical Trainer interview questions

My interview process began with an initial conversation with the talent acquisition lead, followed by individual interviews with two different hiring managers. After receiving an final technical interview invitation, I confirmed my attendance via email. Since I had accepted the meeting on a different account, I was later emailed to confirm my attendance. I responded over the weekend before the scheduled technical interview, confirming that I would be attending. However, it seemed they hadn’t seen my confirmation. On the day of the interview, I joined the Zoom call and waited for others to join. When no one showed up, I called the talent acquisition lead and was informed that the interview had been canceled because they hadn’t received my confirmation. During this call, I was also told that the position had already been filled. Afterward, I forwarded my original confirmation email to the talent acquisition lead, but did not receive a response. This experience was disappointing and felt unprofessional, especially considering the time and effort I had invested in multiple rounds and the effort put in to prepare for the techncial interview.
