Amazon Software Development Engineer (Graduate) interview questions

I submitted my profile on their jobs page in October 2018. In November, I got an email where they told me they won't be proceeding with my candidature. Then in February next year, out of the blue, I got another email saying they were reconsidering my application along with a test link. The test contained Analytical and Logical Reasoning questions along with a section of Code Debugging. Right after this, I was sent another link that contained two more tests. The first was a work simulation designed to emulate a typical day of an SDE at Amazon. The other section had two programming questions related to trees and strings. After this, they invited me to a phone interview round. This contained behavioural questions as well as a coding question. The interviewer also encouraged me to ask him questions. After the phone interview, I didn't get hear for about four weeks from them, after which, they asked me for my availability for an onsite interview. They helped me get a Visa as well as booked hotel and flights for me. Things got a bit delayed over here as Visa processing took more time than typical. I had three onsite interviews which were exactly similar to my phone interview pattern. The coding questions were on the medium side; nothing too difficult. It's important to ask solid questions at the end of each interview and also perform well in the behavioural questions. Two working days after my interview, I received the job offer.
