ServiceNow Advisory Solution Consultant interview questions

Coordination and communication was bad during the process, and deadlines were never respected, I had to follow-up every single time after the deadline has passed. I understand we are all busy but at least a message saying the process will be a bit longer than expected instead of leaving candidates wondering what the situation is would be appreciated. Had 3 interviews, they went well and had very positive feedback from all, and was scheduled for the panel interview, I prepared (ppt + demo) but it was cancelled last minute and was told that they will get back to me the following week to reschedule, what a surprise as I again did not hear anything back so I followed-up to then hear the position has been filled internally but the position has been re-opened the next day. Scheduling a candidate for panel interview, having him prepare a PowerPoint and platform demo to then not even let him present and waste his time is not acceptable. Coming from ServiceNow knowing their reputation is shocking.
