Amazon sr, vendor manager interview questions

I was contacted by a recruiter via LinkedIn. After sending my CV I was contacted my another recruiter coordinator to set up a Kenexa numerical reasoning test (30-45 min but has no time limitation). After the test (never knew the result) I was contacted for a phone interview of 45 min with 2-3 behavior questions linked with the Amazon 14 Leadership principles. Afterward, I did on site on the same day + 4 behavior interviews of 45 min each (in a row). The day after the interviews I've received an email confirming they wanted to make me an offer.

This is after the written examination . The written interview was tough and comprised of three parts . Once I cleared it, someone from the team called and took a telephonic interview .The telephonic was more of a conversation that lasted for 30 odd minutes.
