Amazon Software Development Engineer interview questions

Finished OAs 1-3 before getting a 3x45min interview offer after being waitlisted. They ask so many BFS/DFS questions and I could not prepare enough with the short interview notice... The interviewer was pretty nice (audio quality was terrible tho) and tried to give me hints. It was annoying he would cut my answers for the behavioral questions short and move on. Maybe due to time constraints but it did not feel nice

Three OAs as many others have described already (debugging, 2 LCs, and a work simulation). One 45m final round with an Amazon SDE who asked a two LP behaviorals and one technical question. Waitlisted 4 days after interview, about 10 days after that I was given the option to ask for a Fall internship instead of summer. I expressed interest in this and got an offer two days later. Process itself was rather long (Applied in October, recieved first OA in early Jan, interviewed mid Feb, offer early March). However, I was very impressed with the speed and quality of communication with recruiters whenever I had a question or asked for an update. Made the interview process feel quite personal and respectful despite knowing the scale of their hiring operations.
