ServiceNow interview questions

Only one round. Got a call in the middle of the week saying interview on Friday. It was a panel interview i.e. 3 back to back interviews. One was technical, one was a whiteboard one and last was behavioural.

I was contacted by their recruiter. They had to tell me about the position because I never heard of the role. Its not what I had a background in. They brought me in with one interview. Then a 2nd one. Then told me I had 4 more to do. I did great on most of them. I liked the team and they liked me. I ran over estimate time each time because I hit it off so well. Then they asked for another interview. A seventh interview! But kept rescheduling it with strange excuses. Seemed a lot like breadcrumbing. Finally I ask them if we can speed it up after weeks of delays. They bring me in to talk to someone different from another department who asks obscure technical questions not related to the job. And finally asks me to tell him the entire process flow of a product that I used briefly that has been EOL for more than a half decade. (I wasn't retaining something so far back and dead.) I didn't do well with his line of questioning. A week later they get back to me with a rejection. I ask why. I'm told I didn't have the existing experience they wanted. So I asked "How is that the reason for rejection? YOU reached out to me about this and then caused me to spend multiple vacation days talking to so many people. You saw my experiences posted." and they just said "I guess our requirements changed somewhere in the middle." Pretty sketchy. But at least they gave a reason. So the whole process was an incredible waste of time and energy. Strongly discourage interviewing with these guys. Or at least with this team. If I could get past the enormous waste of time and energy that apparently was just-for-kicks, I would say it was an decent process. For the most part, everyone I talked to was pleasant.
