After applying early September, I received an online assessment two months later to do the generic code debug / reasoning assessment. Two days later, I received a second online assessment to do a 70 minute, 2 question coding challenge. You should be fine if you're solid on your data structures / algorithms. I had a special situation where I had a pending offer deadline from another company, so I attended an Amazon tech talk held on my campus (which I thoroughly enjoyed!) and asked one of the engineers there about my situation. They very quickly expedited my application and had a 45-minute phone interview set up a couple of days later with the same software engineer I spoke to in the tech talk. The engineer asked me one behavioral question and two coding questions. Again, if you have a solid understanding of data structures / algorithms you should be okay, but more importantly you should talk it out and explain what exactly you're coding. I got the offer the next day (the deadline from the other company was the day after I got my offer). Overall, I had a pleasant experience with the interview process and I learned a lot from the phone interview about how to improve as a software engineer.

One online assessment and one virtual interview included a coding round and leadership principle questions; overall, the process was fairly straightforward and not overly challenging for me throughout the experience.
