There are several rounds of interviews in hiring processs. First they asked me to write a small application. That primarily involved to build some logic for identifying all the combinations satisfying a given condition, and had to use Rest Api along with downloading images. Then there was a telephone interview for an hour. Questions were very simple and focused on object modelling, basic java and sql. They also asked me to explain about my project. Asked me to explain about any important decision I took in the project. This was followed by an onsite interview. I was asked to travel to Vegas for the interview. They will plan your travel verywell. Onsite interview was very long. It started at 8:30 am and went till 5pm. Frankly I felt it was very long with several rounds. But I believe the hiring process is one of best ones I ever had. I gives you sense what they r looking for and gives you an idea how people are at Zappos. Here is how my whole day at Zappos went. For first one hour they gave the tour of the company, showed us different departments. It was quite useful to know work culture at the company. After that I had four technical and one HR(behaviorial) rounds. In two rounds they asked me to write algorithms like reverse a linked list, tree traversing algorthms, permutation and combination algorthms. They asked additional questions like time complexity and write alternate algorithms. You may also have to discuss about performance of what you write. Second one was coding challenge, they asked me to write code to implement Lift. They give you one hour of time and would expect you it to run. Third round lasted for 2 hours in which they focus on how you model and design applications. They give many applications, tweet it in different ways and ask you how would you design the system for each of them. I felt it very interesting but I felt it verylong. HR asked many questions to see if your fit to the company work culture. It was of different kind n cool
