El proceso duró 1 día. Acudí a una entrevista en Amazon (Seattle, WA) en ene 2012

Which of C++, Java languages supports Multiple Inheritance and which does not ? Follow up: What do you think of Java not supporting Multiple Inheritance?
C++ supports multiple inheritance of classes, Java (and C#) supports single inheritence of classes and multiple inheritance of interfaces.
When C++ added multiple-class inheritence pure OOP was thought to be "the" solution to everything.
In the meantime it was proven that class inheritance is good, but it ends up with tightly coupled systems. The more class inheritance you use, the more likely that one small change will have a huge impact on your entire system.
Loosely coupled inheritance - interfaces - are considered a much better option these days.

Given references to roots of two binary trees, how do you short circuit determine whether the sequences of the leaf elements of both the trees are same ? The structure of two BTs may be different. Short circuit : for ex. If the very first leaf element of each tree is different, the algorithm should stop immediately returning false instead of checking all the leaf elements of both trees.
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.

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.
