ServiceNow interview questions

I applied for the UX lead role. The recruiter was very engaging at first, but it required quite a bit of follow-up after the initial call that they confirmed a second interview. Before the second interview, another recruiter sent me the wrong information about the interviewer ( wrong name, wrong person). So I addressed the interviewer during the interview with the wrong name. They ghosted me for a while after the interview. I eventually chased so many times to find out they moved on with no constructive feedback.

Relatively easy interview. Total 4 interviews and all had coding questions except the first screen with recruiter. Each interview was an hour long including the final interview. Even though it was a front end role, didn't get asked any technology related questions (i.e react based or javascript based questions.) All questions were just algorithm questions). Didn't get asked any system design questions. Last interview went south for me as I used an approach that wasn't very efficient to solve for merge two sorted arrays.
