Amazon does not hire ordinary. To ensure that this statement holds true, Amazon trains a selected few of its employees to be Bar Raisers in the Amazon interview process.
These Amazon employees take on essentially a second, unpaid job as candidate evaluators. Apart from taking one of the interviews, the primary job of a Bar Raiser is to ensure that for each position and level, every candidate is being interviewed across a shared set of competencies: the 14 Amazon leadership principles more about them in a while. The BRs also help by discovering hidden hiring motives, like a serious near-term need, and force interviewers to reconsider their feedback in different contexts.
Bar Raisers are known not to jump from one question to another, but savour hearing every applicable detail of your story in the Amazon interview process.
Amazon usually conducts about four to six interviews, wherein at least one interviewer is a bar raiser. Each interviewer covers a few of the 14 Amazon leadership principles so that in entirety the candidate is judged on each one of them in the process.
Behavioural interview questions are asked to check if the candidate has manifested these 14 amazon leadership principles in the past. As stated earlier, these are the single most important filter that Amazon uses to select candidates in the interview process.
Amazon strongly believes that with the expansion rate of the company, the only way they can keep the company culture alive is by ferociously guarding their 14 leadership principles. If even one of the BRs has an objection to Amazon hiring the candidate, they can simply veto the application and the interview process ends there. These Principles work hard, just like we do. Having interviewed Amazon recruiters and candidates, we have collated a brief list of interview questions that are used in Amazon interviews to judge candidates on each of these 14 leadership principles.
Please note that the interview questions below are by no means exhaustive and are just indicative of the space that your Amazon interview questions would be penetrating into. You can use this list of interview questions to work on your laundry list of experiences and pick out your star stories: the stories that best manifest the Amazon leadership principles you want to put light upon.

An Authorization Code grant allows a client typically a website to direct the user-agent a user's browser to a URI at Amazon. The user is then presented with a page asking to grant the website permission to the user's profile. After the user approves the request, the client receives the authorization code and can trade that code for an access token and refresh token.
The client will then receive an Authorization Response described below. After the client website directs the user-agent browser to make an Authorization Request, the authorization service will redirect the user-agent to a URI specified by the client. If the user granted the request for access, that URI will contain a code parameter containing the authorization code.
For example:. The authorization code can range from 18 to characters. An authorization code is valid for 5 minutes. The redirect also copies the state passed by the user-agent in the authorization request. This value allows you to keep track of the user's state before the request. It is also used to prevent cross-site request forgery.
That URI will contain error parameters detailing the error. The following error codes can be returned as the value for error :. After the client website receives an Authorization Response with a valid authorization code, it can use that code to obtain an access token.
With an access token, the client can read a customer profile. This is because that exchange requires the client secret, which should not be stored in a script. As a result, your web server will need to make the exchange instead. If you use amazon. For more information, see RFC When you obtain an access token, you will also receive a refresh token.

OA3: Work place simulation, you'll be given several scenarios that can occur in the work place.

He asked me for run time and space complexity for both which I was able to do. I got nervous at first explaining my first problem and did freeze a little when explaining my first problem. I did gathered myself for the second problem and was able to answer all his questions he had for me.
