I applied through an employee referral. The process took 6 days. I interviewed at Amazon (Seattle, WA) in Jan 2012
Interview
My friends hand in my resume and I get the on-site interview directly.
The interview process is basical, first have a lunch with several amazon employee. Then each candidate was brought to the room and start the interview. I had four interviews in total, and I did perfectly in the first one, the second one and the last one. I think they fail me because I didnt do well in the third one. So, just bear in mind that Amazon is very picky, if you screw up one of the four interviews, then you fail.
Interview questions [4]
Question 1
How to save a dictionary.
Easy one, just use a trie. During the process, you will be asked questions about big O stuffs. Just remember your data structure
How to find every word in one paragraph and return back the 10 most frequently words.
Easy one again. Use a hashtable to store the words, after that, use a heap to return the 10 most
Numerical Roman numbers.
I screw up this one. That's because the interviewee gave me a sheet full of rules, but only two of them are useful in the first part.
First part: given a formatted Roman String and convert them into numbers.
Easy one, but I spend nearly 25 mins on it.
Second part: how to convert a number into Roman Strings.
Recursion will work. I only have ten mins, so the interviewee doesnt let me finish this up
You have a node, each have three fields: value, next and random. How to make a deep copy.
The interviewee is helpful, he gave me hints and I finally solve it. First copy the list with only value and next. Save each one in the hashtable. And then change the random value.
It started with an OA, and then after a few weeks, I got invited to four rounds of interviews: technical and behavioral at 3 of the 4, and behavioral only at one.
Um teste de código online, se aprovado, vai para o loop. O loop é 4 entrevistas seguidas, duas em inglês e duas em português. 3 entrevistas técnicas de código, todas as 4 têm pergunta de liderança.
Interview questions [1]
Question 1
Pergunta historicas baseada nos principios de lideranca da amazon.
The whole process stretched over nearly a month, longer than I anticipated. After an initial phone screen, I faced a technical round that included a Min Stack implementation question. We discussed design considerations and thread safety, which threw me for a bit. Fortunately, I remembered a specific mock interview I practiced on PracHub that mirrored this scenario closely, making me feel more at ease. Ultimately, I received an offer, but I chose to decline due to the company culture not feeling like the right fit.
