Amazon PM interview questions

I had an interview with Amazon UK for a product management role. After passing the first round, the recruiter inquired about my availability for the loop round (interview with 4-5 members within a day or two). After waiting for three weeks, they told me that before the loop round, they wanted me to talk with another interviewer. I resubmitted my availability and passed the second round as well. So, after passing each of these rounds, I resubmitted my availability for the loop interview, only to find out after three weeks that the position has been removed. This whole process took 3 months, and it was a huge letdown. The recruiter expressed regret and offered to forward my resume, but this never happened. It's surprising how they take someone's time and effort for granted specially during a pandemic like this. It's amazing how they take someone's time and effort for granted, particularly in the midst of a pandemic.
