I applied through a recruiter. I interviewed at Amazon (Peking, Peking)
Interview
I'm applying for an android mobile development position.
First round: two InterviewStreet online test. Very simple.
Second round: One-hour interview with the hiring manager.
* behavioral question: What's the project that you think shows your technical ability the most?
The interviewer just want to hear my detailed description, but didn't discuss further with me about where to improve.
* coding: Given a string (0-9a-z), use run-length encoding to compress it. For non-consecutive letter, don't put 1 behind it in the compressed string.
Third round:
* Simple implementation of DFS/BFS
* Given one day's stock prices, find the buying/selling point that maximize the profit. (I've met this problem before, so the interviewer gave another one instead)
* Substring search, brutal-force and KMP. If the original string is very very large, how to optimize
Fourth round, HR: How are you doing this your current company? What's your major achievement (in technical detail)? Why want to change? Why choose Amazon? Why this position? What's your current salary and your expected salary?
Fifth round:
* Design a toll system for highways
* Same stock price problem with the third round
Sixth round:
* Describe the design of your little android game (I did some android dev causally before)
* Describe the design/architecture of one of the feature/system you own in your previous work. The interviewer will try to understand and propose some improvements, and you will try to give some solutions.

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.
