Amazon Software Engineer II SDE2 interview questions

Supposed to be a 4-hour interview, actually lasted 4.5 hours, 3 hours of behavioral questions about leadership principles and resume in total(including a 1 hour dedicated behavioral round, and about 30 mins for every other round)

The process has taken 2 months so far, I had a first round phone interview after completing an online assessment. Overqall the process is erlatively slow but this is normal for bigger companies.
