Le processus a pris 2 semaines. J'ai passé un entretien chez Amazon (Seattle, WA) en juil. 2011
Entretien
Applied by Amazon we-site, got a call 2-3 weeks after. Passed the first phone interview, week after - one more phone interview, week after - rejected.
From my point of view the first was not good, i did not expect the success result. The second was good from my point of view, but...
Questions d'entretien [3]
Question 1
The first int: Create Queue class based on Stack (suppose Stack is already written and has basic methods). Change the class for using in multithread env.
The second int: You have a file like this:
asb
stop
sba
tops
.....
Write the program, which prints:
asb, sba
stop, tops
...
OK, you have 100gb file - approach? Using pure java? Why you use HashTable, not HashMap? What the difference? White sort for string (you use it in the algorithm)
The phone screen went longer than expected, focusing heavily on implementation details. The interviewer really grilled me on my approach to a Least Recently Used (LRU) cache, asking how I'd combine a hashmap with a doubly linked list. I felt well-prepared since I had gone through system design examples on PracHub, which made me comfortable discussing eviction policies. The later rounds included more technical questions and behavioral interviews, but in the end, I received an offer, though I ultimately decided to decline. Overall, I’d say the process was average, with solid questions.

Question 1
Design and implement a Least Recently Used (LRU) cache supporting get(key) and put(key, value) in O(1) average time. Walk through combining a hashmap with a doubly linked list, eviction policy when capacity is exceeded, and how you'd extend it to handle thread-safe concurrent access.
Recruiter reaches out after applying through Amazon careers, no referral. Had an initial OA, then after a month had four rounds in two days - three coding one system design. Each round had 30 min behavioral and 30 min coding.

Question 1
Questions were mainly hashmap, sliding window and interval related.
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.
