Amazon Applied Scientist interview questions

First round phone technical interview, asked 15 minutes of coding and then 45 minutes of ML technical. Then virtual on-site with 5 rounds including bar raiser, ml breadth, ml depth, coding, etc

Contacted by the recruiter about a month after I submitted the application. and put in an interview with two of their employees, it seem a bit mismatch in the interview the interviewer does not seems know my research area so become difficult to communicate.
