Amazon Process Analyst interview questions

The interview was in 2 stages, one phone interview and one in-person interview at Amazon. Phone interview was about 1 hour asking technical and softskill questions, easy to answer. After 2 weeks I got in-person interview at Sydney. The scheduling was poor and HR have not noticed I live in another city. One day before interview they asked me to so the interview online. Anyway I decided to travel to Sydney as I was already prepare for it. 5-6 hour interview day with 4 people which was very demanding and I ended up with headache. After 10 days and several followup with HR , I was not accepted and Amazon didnt pay for my interview trip. It costs me around 500$ and 3 weeks time.
