Amazon Software Development Engineer interview questions

Started with email from Amazon recruiter. Submitted resume, got invited to online assessment. I thought I screwed up 2nd question (shortest path through 2D maze), but got invited to onsite. 1 hour meet the team at 8am, 4-50 minute interviews back to back. Each interview asked some behavioral questions, the 3 had coding exercises and 1 had system design. I think I did well with experience, leadership, and system design - but struggeled with coding. And two of the three were pretty easy questions I think is psyched myself out before the interview and that didn’t help. I tried to come with optimal solution right away rather thank work through simpler solution and wait for follow ups.
