What Is Verification And Validation

How I cracked amazon’s QA interview? Interview Process and Tips

Validation is where the process of evaluating the end product takes place. This is done to determine whether the software meets the companys needs. Quality assurance teams typically perform validation activity by testing the execution of a product daily. This includes systems testing, smoke testing, regression testing, and functional testing. Verification is essentially the process of working through the development lifecycle’s intermediary work products to see if everything is going according to plan on time for the products release.

What Do Qa Interviewers Look For In Candidates

You dont need to be an incredible wunderkind or world-famous expert to prove your worth to a potential employer. Many times, an employer wants someone who fits the team and is willing to apply themselves even if they dont tick all the boxes for a position.

A willingness to grow, learn, and push themselves is the best quality for QA job candidates. Its fine if this particular position may only be a stepping stone for your career, but dont let your interviewer know this.

The company is about to invest thousands of dollars into you. Dont start off with I think this is where I want to be. Youll never get hired that way. I myself wasnt sure I was going to stay in QA, but here I am15 years later and Im still in this field. You never know what the future holds, so be confident and give this field a shot since you never know what can happen once youre in it.

How To Be Successful In Amazon Qae Interview

Before I jump into the main article content, I would like to do few things first, two things in particular.

Firstly, my sincerest apologies to those people who messaged me requesting the details pertaining to how Amazon’s QAE interview would be like and did not receive a reply from me. I tried replying as much as I could :(. Especially, I replied to all those messages that said their jobs were impacted or about to be impacted due to current COVID-19 situation. My heart goes for you all.

Secondly, a few disclaimers. Please note, I am not representing Amazon here and your interview might completely go south . Also, I am not endorsing anyone towards any job at Amazon . I know that there are other great organisations with even greater products than of Amazon.

The main intent of this article is to help the needy Amazon QAE interview prospects with relevant information and guide them to be successful in their interview attempts with correct preparation.

What Do You Understand About Data Driven Testing

Amazon Software Qa Engineer Interview Questions

Data-Driven Testing is a software testing technique that stores test data in a table or spreadsheet format. Testers can use data-driven testing to enter a single test script that can run tests for all test data from a table and expect the test results to be returned in the same table. It’s also known as parameterized testing or table-driven testing.

Because testers usually have several data sets for a single test, Data-Driven Testing is critical. Creating different tests for each data set can be time-consuming. Data-driven testing allows data to be kept separate from test scripts, and the same test scripts can be run for multiple combinations of input test data, resulting in more efficient test results.

The above image depicts the process of data-driven testing. Test data is taken from a data file and tested on the application and then the produced output is compared with the actual output.

Describe The Differences Between Negative And Positive Testing

Negative testing is a testing technique that makes sure that the system works optimally in the case of any invalid inputs. For example, a user may enter invalid data into a text section. The application should return with a correct message, rather than a technical message the user will not comprehend. Positive testing determines that the system is working correctly and compare expected results with the actual testing results. Too often are negative testing scenarios not included in the determined product plan, so it is the duty of the quality assurance engineer to identify those negative scenarios and test for them.

The interviewer mainly checks the ability how you solve problems and perform debugging, including how you solve algorithmic problems. You can use any programming language that you know. Basic analytical skills and data structure knowledge will help you complete your tasks successfully. You may encounter questions like “How to debug a website that gives 404 errors?” or “How would you check why a user cannot add an item to the shopping cart?”. Here, you need to think deeply and devise a viable solution.

Has Anyone Taken The Amazon Qa Engineer Code Test

I have an interview next week with Amazon for Qa Engineer and there’s a coding portion. Has anyone taken it? Any tips to prepare for it?

I did about 7-8 months ago. They asked me a few basic questions like what’s a test plan and then asked to develop test cases for a feature they described. Then came one of those typical whiteboard questions off leetcode.

I don’t remember the exact question, but it involved Arrays and the interviewer wanted me to code a Binary Search Tree on CoderPad as part of the optimal solution… I wasn’t expecting that.

Good luck! 🙂

What Do You Understand About Bug Leakage And Bug Release

  • Bug Leakage: When a bug is discovered by an end-user, that should have been caught in earlier builds/versions of the application, a bug leakage occurs. Bug leaking refers to a fault that exists during testing but is not discovered by the tester and is subsequently discovered by the end-user.
  • Bug Release: When a particular version of the software is released with a collection of known bugs/defects, it is referred to as a bug release . Bugs of this type are frequently of low severity and/or priority. When the company can afford the existence of a bug in the released software rather than the time/cost of repairing it in that version, this is done. In most cases, these bugs are disclosed in the Release Notes.

How Do You Prioritize When You Have So Many Tasks

Think about how youve approached busy moments in the past. Are you a strict scheduler? Or do you prefer budgeting your time more loosely, allowing room to adapt to sudden issues? Again, these questions are more about determining whether youre a good personality fit for their team.

If youre somebody who feels that prioritizing multiple projects is one of your weak points, the Harvard Business Review has a guide on how to properly prioritize at work.

Explain What Is A Testware In The Context Of Quality Assurance

Testware is a collection of software created for the specific purpose of software testing, particularly software testing automation.

For example, automation testware is created to run on automation frameworks. All utilities and application software that work together to test a software package but do not necessarily contribute to operational purposes are referred to as testware. As a result, testware is only a working environment for application software or portions thereof, rather than a static configuration. It contains artifacts created during the testing process that is needed to plan, develop, and execute tests, such as documentation, scripts, inputs, expected outcomes, set-up and clear-up processes, files, databases, environment, and any other software or tools used during testing. Both verification and validation testing methodologies are used to create testware. Testware, like software, consists of codes and binaries, as well as test cases, test plans, and test reports. Testware should be preserved and faithfully maintained under the direction of a configuration management system.

What Is Monkey Testing

  • Monkey testing is a type of black box testing used to test the application by providing random inputs to check the system behavior such as to check the system, whether it is crashing or not.
  • This type of testing is performed automatically whenever the user provides the random inputs to check the system behavior
  • There is no need to create test cases to perform monkey testing.
  • It can also be automated, i.e., we can write the programs or scripts to generate random inputs to check the system behavior.
  • This technique is useful when we are performing stress or load testing.

There are two types of monkeys:

  • Smart monkeys
  • Smart monkeys are those which have a brief idea about the application.
  • They know that where the pages of an application will redirect to which page.
  • They also know that the inputs that they are providing are valid or invalid.
  • If they find any error, then they are smart enough to file a bug.
  • They also know that what are the menus and buttons.

Dumb Monkeys

  • Dumb Monkeys are those which have no idea about the application.
  • They do not know about the pages of an application will redirect to.
  • They provide random inputs, and they do not know about the starting and ending point of the application.
  • They do not know much about the application, but still, they find bugs such as environmental failure or hardware failure.
  • They also do not know much about the functionality and UI of an application.

Should Qa’s Resolve Production Issues

Amazon Software Qa Engineer Interview Questions

You might have varying opinions on this one, but I’d advise you to answer “Yes”.

Its often good for the QA to be involved in solving production issues. They should, when possible, write test cases and try to find the issues. By getting involved, the QA is minimizing the number issues in the final product.
