Amazon sr Technical Program Manager interview questions

I don't have experience as program manager and in my resume its not mentioned. i worked as technical lead and architect. I got call from Amazon recruiter saying my resume is shortlisted for senior tech. program manager. And first round they sent assignment via mail about business scenario and asked few questions related to this I have spent time 2 hr and answered and sent the updated document. I got call from Amazon,Bangalore recruiter saying I was scheduled face to face round at Amazon office near MG road,Bangalore . I reached MG road at 12 PM and first round is technical round with questions on design, architecture etc. and question on design of online portal etc . Its around 1 hr and after this HR person asked me to wait for further rounds . And they provided packaged lunch at their office. 2nd round started at 1 PM and questions on team management,project mgmt etc. 3 rd round for 45 mins to 1 hr and questions on project mgmt, innovative things I have done etc. 4th round again some repetitive questions on project mgmt . By the time interviews ended its 4.45 PM. Recruiter told they will provide feedback within 2 to 3 days. I got a call from HR saying my 5th round is scheduled at WTC office at Yeshwantpur on next Monday around 12 PM. It took around 2 hrs to reach that place from Outer ring road,bangalore. 5th round I was asked about questions related to my project architecture,conflict mgmt and project mgmt etc. it's for around 1 hr.After this recruiter told they will provide feedback within 3 or 4 days .And I got mail saying "we regret that we do not have a suitable opening at present that does justice to your aspirations and capabilities Hence we would not be able to take it forward at this juncture." I applied 2 days leave to office to attend interviews. Initial assignment which was never talked or discussed in interviews :(. Amazon can spend lot of time on interviews as they can afford but we cannot spend that much time. They provided cab pickup/drop facility.My suggestion try amazon only after you have offer from another company . As after spending this much time you will be disappointed if you didn't get through.:(
