Amazon Business Analyst interview questions

First step interview with HR, I thought that this interview is with people in main team, title of my last position and position that I applied for that were same but job descriptions were totally different.

This position was in the Risk and Compliance Services (RCS) team. First call with the hiring manager, with a 'surprise' SQL test straight away. The test was not that easy, requires strong SQL skills (self-joins etc). Then second round with 4 interviews (!) with 3 members of the team + one from another team. They were supposed to be only behavioral interviews, but I had to do another SQL test for 30 mins in the first of these 4 interviews. Overall the communication with them is rubbish. It took them over 3 weeks to schedule these 4 interviews. The last interview got confirmed the same day, 3 hours later! Declined it since they salary offer was £13k below what I expected (despite giving them my salary expectations from the start of the process). Waste of time with unprofessional people. Such a shame for Amazon.
