Amazon Software Engineer II SDE2 interview questions

Alexa team recruiter contacted via LinkedIn. After the initial phone call. was given an online assessment. 1. online assessment on coding and behavior 2. 3 coding on data structure and OOD and 1 system design for scalability and availability.

Pathetic experience. More than 2 months. Attended 1st round (online assessment) on 27th March. No communication from the HR . Just a mail to complete the online test. After several mails the HR send a mail your result is inconclusive.we will conduct another round please share your availability. But after sharing my availability No update or reply from HR after several mails for more than a month and suddenly on May 11th got a mail for onsite round on 12th( next day). There’s no communication from HR on call or on email. Attended the 3 onsite round in 2 weeks. All the 3 rounds were canceled and rescheduled 5 times in total. 3 times after joining the meeting the interviewer didn’t show up. After completing the 3 rounds did 4-5 mails to the HR but no reply from any of the contact persons (1st, 2nd 3rd contact were there) then had to reach the HR on LinkedIn and after 3 weeks she finally reply you are not selected. What is this process? Is it even an interview?
