I applied online. I interviewed at Amazon (Boston, MA) in Nov 2020
Interview
The OA questions are mostly classic, but some questions took some time to understand, algorithms like sorting algorithms and ranking algorithms are frequently used, and many types of data structures are also included
Interview questions [1]
Question 1
How to find the number corresponding to a certain rank in an array
First round 2 leet code questions , second round easy array questions, interviewer was warm; helped me through the process asked me behavioral about my latest experience and then the response came within a couple of days
I applied through a recruiter. The process took 4 weeks. I interviewed at Amazon in Feb 2021
Interview
I applied through a recruiter. Sent me an online assessment, 2 leetcode medium questions to finish in 90min, with 2 articles to explain the approach and complexity analysis. Time is really tight. Each question need to:
1. understand question in 3min,
2.come up a solution in 2 min,
3.finish coding in 15min,
4.adjust to edge cases in 15min,
5. then document the solution in 5-10min.
If the first solution you came up with is not good enough, you are pretty much doomed -- no time to do it again.

Question 1
Do you think you can work under pressure?
Understand data structures such as graph, linked list, array, hashmap.
