    Difficult Interview

    Application

    I applied online. The process took a week. I interviewed at Amazon.com (Seattle, WA) in July 2012.

    Interview

    I applied online to many of their job postings, got a call from HR after a month. They had an hiring event , so after HR screening, they called me directly for in-person interview. Interviews started on time. I had 4 technical , 1 behavioral and 1 HR round, each for around 40-45 mins. All the interviewers were very helpful. At no point I felt uncomfortable. When I got stuck, they provided hints to help me arrive at answer. Overall a good experience in interview, they confirmed selection on same day and I got offer letter within a week.

You are standing at top left intersection and you need to reach to a resort located at bottom right intersection. On your way, you can see interesting sights which are given points (weightage). You are lazy to walk (i.e. you wont walk left / up. You will only walk to right or down). While reaching resort , you want to cover maximum points (see things that have more weightage). Write a program to calculate maximum number of points that you can cover. He later asked me to improve solution by avoiding paths already visited.   1 Answer

    Difficult Interview

    Application

    I applied through a staffing agency. The process took 2 weeks. I interviewed at Amazon.com (Chennai (India)) in April 2011.

    Interview

    It was pretty well organised. They gave a good overview of what is expected in the interview so that we can be prepared to take it. They concentrate more on problem solving and the data structures where though they don't expect you to immediately answer the questions they wanted to make a genuine try and valuate the approach.
