Software Engineer Interview

Anonymous Interview Candidate in Austin, TX
Anonymous Interview Candidate in Austin, TX
Application Details

I applied online. The process took 2 weeksinterviewed at Amazon.com in August 2014.

Interview Details

Initial Communication - One of their technical recruiters messaged me on LinkedIn expressing an interest in my skills. I ignored it. A couple months went by, and I decided looking for other career opportunities would be a good thing. I applied online for their Austin, TX positions. I also found a few of their technical recruiters on LinkedIn and messaged them.

I got a phone call from one of their technical recruiters. She was really nice and excited to talk to me. There were a couple questions about my work experience mostly to make sure that I was who I claimed I was on paper. The next step was a timed test online that they would record in real time. She also gave me a small document that was prep for the test listing various topics that the test would include. She also claimed 'do not exceed one hour' on the timed test.

To prepare for the test, I recommend googling for Amazon Test questions. They won't be exact, but you'll get in the habit of answering questions fast. The test was composed of three questions. 1) Write a series of classes for a graphics API. 2) Implement a breadth first traversal of some tree. 3) Implement a method for the fibonacci sequence.

Then a couple phone calls and email exchanges. "You Passed, we love you!". The next step is an onsite interview that lasts 2-4 hours.

The onsite interview consisted of meeting with pairs of people. One of them was the lead interviewer, the other was someone who had started within the last six months and was there more to take notes. The first group seemed unhappy to be there at all. It didn't matter what I said. It was straight to the white board for more technical tests. This group asked questions about implementing a bit map editor. They purposely would ask vague questions with the expectation that you will ask them questions to figure out what they are really wanting answered. They would ask questions about big O notation. They would ask questions about memory usage. The next group was similar.

I asked each of the groups if they would be my actual coworkers. The answer was no across the board. I did want to meet whom I would actually be working with. The people I met in the interview seemed like they didn't want to be there. Toward the end of one of the groups, I thought of a better implementation to a question I answered. They responded, "We're out of time". They definitely had the attitude of "People apply here everyday, Anyone is replaceable, No one is unique"

I'm guessing I didn't pass their in-person technical test, but I wasn't too crazy about working with them either.

    Interviewed with 5 people total. One of them was very nice and friendly. All the others were impersonal and mechanical. Could tell it was a everyone man for himself kind of culture.

    It was a good experience over all. Know your basics, algorithms, sorting and searching techniques, know at least one programming language in and out. Think clearly, code correctly. Relax the night before, and prepare well in advance.

    Applied on the site, recruiters contacted with in a few weeks. The overall experience was negative because I felt the interviewer was a bit rude. I've interviewed with Apple, Google, FB as well and all the others have been positive experiences regardless of how the interview went.

    Application Details

    I applied online. The process took 7 weeksinterviewed at Amazon.com in May 2014.

    Interview Details

    Evertyging was very cool experience, I applied in the website, two weeks later they contacted me for a phone interview, so after that first contact passed 1 week for the phone interview and then 1 week more they contacted me again, they wanted an onsite interview, in 3 weeks. So I got ready for it.

    I went the day of the interview, everything was nice, normal questions about design and algorithms, so far my day was excellent I felt like I was answering ok, until the end of the interview, it was at 3 pm, the last interviwer was late, I was waiting for him, he came more than 20 minutes late ( 3:22 ), then he apologized, then he gave me a question, I was in the middle of the answer when he said, its ok, i think we are out of time, and i felt kicked out ( 3:28). The last interview was only 4 minutes? I think he had a load of work or other appointments, I did not think I was answering that bad, the worst thing is I think he was the bar raiser, and I think I depended more in that interview than the others.

    I don't know if its related, but the next day I lost a call (I was busy), from a back ground check company, since Amazon was the only company I was applying I imagined it was from them.

    Two days after the on site interview they called me to say that they had no offer, but they wish I could apply again in a few weeks. I did not, since it took me 6 weeks preparing for the interview, so I lost interest.
