I applied online. The process took 3 weeks. I interviewed at Amazon in Oct 2012
Interview
Two standard phone screens with different developers. First interview asked simple concepts and practices associated with object oriented programming. There was also a heavy focus on data structures. Since Amazon is a global company, they are interested in scalability and efficiency when it comes to development.
First Interview Questions:
1) What is encapsulation and polymorphism?
2) Describe linkedlists, arrays, stacks, queues, priority queues, heaps, and binary trees. What are their complexities and benefits?
3) On a server in a directory with 50,000+ HTML files how would you find and return a count of phone numbers?
4) What is the difference between binary and hex decimal?
5) Design/Code a method that multiples two numbers without using the multiply operator. And what are some tests you would implement (i.e. black box, white box)?
Second Interview Questions:
1) Given a list of acceptable words (dictionary), how would you check to see if a given input is on that list? Complexity and efficiency?
i. How would you complete this task with a dictionary that is too large to fit in ram? Complexity and efficiency?
ii. Now given two input words how would you find and return all available words in between the two words? (i.e. input1= "Cat", input2= "Fish", return all words in between) Complexity and efficiency?
2) Given a singlyLinkedList, write a method that reverses the order of the list. Complexity and efficiency?
Interview questions [1]
Question 1
Just make sure you cover all your basics. They will cover a wide range of topics to see what you know and how you react to difficult questions. Always ask to clarify questions since they are usually ambiguous.
Interview by recuriter, Phone interview over Chime with one easy Leet code problem and 2 behavioral questions. Although the interviewer was very casual at the start of the conversation, it quickly changed into behavioral questions at the start.

Question 1
Encoding optimization algorithm and talk about a project you did recently.
First round is just leet code coding which screens through AI before going into live coding. Pretty simple and straighforward. Not too tough. Recruiter walks through it pretty nicely. Not sure how many rounds there are exactly
After submitting my application for the Software Engineer position, I received an invitation to complete an automated Online Assessment (OA). The assessment consisted of standard coding challenges, primarily focusing on algorithmic and data structure problems. Unfortunately, a few days after submitting my solutions for the assessment, I received an email informing me that I would not be moving forward in the interview process and was rejected.
