Amazon Technical Writer interview questions

I got a call from an Amazon recruiter for the position of Technical Writer I for Bangalore location. I was interested so she scheduled my interview. The first interview was a video call with an senior technical writer who asked me behavioural and situation based questions. Amazon is known to have a unique interview process where they ask questions to judge candidates on the basis of their Leadership Principles. I cleared the 1st round and next round was a written assessment. It included English writing and editing questions and some basic HTML coding questions. After clearing the assessment, i was invited for the third round which was again a video call. At this point the recruiter tells me there will be a total of 5 rounds. I cleared the third round too and scheduled the last two rounds. Unfortunately the interviewer didn’t for the 4th round. When i called the recruiter to follow up she said Amazon has declared a hiring freeze and they are not entertaining any more candidates. I was shocked to know this at the last moment. More surprising was that the recruiter didn’t have the courtesy to call me beforehand and tell me that the interviews will not take place. I was given a meaningless apology and thats it. This came after Amazon had laid off 10k ppl 2 days ago. If there was a hiring freeze wouldn’t the recruiters know already? Why was i not informed before.
