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.
Great interview process with three rounds, including a technical assessment and a technical interview. The interviewers were professional and supportive throughout the process. The questions mainly focused on DSA, problem-solving, and core technical concepts. The discussions were engaging and provided a good opportunity to demonstrate technical skills. Overall, the process was well-structured, smooth, transparent, and a very positive experience.
I applied online. I interviewed at Amazon (Sydney)
Interview
I can't comment much. I submitted an application for the software engineer position, and not even a minute later, I received an auto rejection email from Amazon (never received an online assessment).
2 behavioral 2 coding not very difficult. Behavioral is tell me about a time you took responsibility beyond your role and biggest accomplishment. The process is exactly the guideline they posted for interview.
