Software Engineer Interview

Anonymous Employee
Anonymous Employee
Application Details

I applied online – interviewed at Amazon.com.

Interview Details

The process started out with taking an easy online assessment of 7 questions. After that was completed I had an over the phone technical interview that lasted for about 45 minutes and consisted of one multipart question. The interviewer was helpful in getting me through parts of the problem which I stumbled on and over all it was a good experience. Other than the technical question the interviewer was also very interested in what I have done outside of school (programming oriented side projects in particular).

    I applied online. The process took 4+ weeksinterviewed at Amazon.com in March 2015.

    Interview Details

    I applied online on amazon.jobs, but their online job board is crappy and full of bugs. After one week, I got email from Amazon.com recruiter from India, wanting me to do their code assessment from HackerRank.com. There were 10 different coding assignment that you need to complete in very less time. Out of 10, 9 of them were correct but did not get time to finish the 10th one. I emailed the recruiter who lived in India that I finished the code assignment and I got email stating, he will sent to team for review. After one month, I did not get feedback. I emailed him after one and half month, another recruiter from India stated on email that I am not being selected. Basically they are not looking for human, but Robot to do their software engineer work. Their interview process is JOKE!!!

    Interview Details

    One set of 2 interviews, 45 minutes each, then received a yes/no decision a week after those two interviews. Despite receiving a copious number of emails (9) to set up the on campus interview over the span of a month, I still did not know the location of my interviews the morning of. Also never received a response to my emails requesting clarification. Had to show up 15 minutes early, search the building, and ask somebody to find out where I was supposed to go. Had two 45 minute interviews, each had a technical question and general discussion of previous work. During the second interview, the interviewer took 5 minutes to set up someone else's interview that had been poorly organized.

    Interview Details

    Pretty fun initial online test with two coding questions and then a bunch of more logic based IQ questions. Both portions had a time limit. For the coding portion of the test you had to write compilable code to properly output the expected results. The questions very fairly simple bit manipulation and data structures.

    The interview wasn't bad. The initial interview was an online test. The coding part wasn't too bad. The multiple questions were time consuming though. The questions are small initially. Then they start getting huge and realize that should not have spent time on the smaller questions.

    After waiting for about 1 month, they email me to take an online accessment. OA contains two programming problems and 24 logical and reading problems. Two programming problems are grey code and string rotate.
    One week after OA, they email me to take a workstyle survey which has a lot of character problems. This part is simple.
