ServiceNow Senior Software Engineer Frontend interview questions

The recruiter approached me through LinkedIn and asked me to share my updated resume. Received call from the recruiter after one week and they explained about the interview process and about the company. There were total of 4 rounds of interview. In the first round, interviewer covered all the javascript concepts and also gave couple of basic coding questions. In the second round, the interviewer focussed on programming. He asked questions involving trees and arrays. The third round was a design and coding round. I was asked to design a small web app and implement the basic functionality using vanilla javascript. 4th round was with hiring manager and it was techno- managerial round. He gave some sample json data and asked me to write js code to get the desired output that he has shown. Also asked some behavioral related questions. The recruiter called me couple of days later and said I cleared all the rounds and asked for my expected salary. As I had another offer in-hand, I explained the same and gave a rough expected salary. The recruiter said they would see what they can do and let me know. The recruiter did not contact me again.
