ServiceNow interview questions

These servicenow interviews are only for time pass purpose .i went to interview on saturday. i got rejected for no reason. they asked me to write code for finding loop in a linkedlist. i have written but he said you can leave for the day. I couldn't understand what is my mistake. just i want to give small suggestion to servicenow if you really dont have any requirement please don't waste our time. this will give us disrespect on organization. i heard from my colleagues they also faced this issue with servicenow.

1. Worst interview process ever faced at ServiceNow hyderabad.Beware of these cheaters. 2.HR doesnt set any proper expectation and just randomly calls for interview.Many people left without attending interview. 3. A girl(who thinks herself as an actress) took the interview.She doesnt have any knowledge,sense or experience of taking interviews. She felt like she has learnt by-heart all the questions on which she could find on AngularJs from internet(herself unaware of answers☺). I gave her best answers and she nodded her head with uttermost satisfaction throughout. In between that silly girl was texting her someone..and didnt listen to my answers also. She asked the difference between Bootstrap and Angular?? Isnt it silly?I still explained just for her knowledge..Explained all answers for half an hour except one question on linked list cyclic loop check in javascript for which she was unable to explain the question also in 5 times.. I was asked to wait for some time and then said u can leave with statement as WE ARE LOOKING FOR PROBLEM SOLVING ABILITIES,without a single problem given to me to solve???????
