What Do You Understand By A Test Script
A test script is an accumulation of instructions needed to be performed on a given system to determine if it functions as it is supposed to. It, therefore, guides the testing process and can alternatively be defined as a short program that tests a given portion of a software products functionality. It is also worth mentioning that a test script can also be referred to as an automated test script, given that the testing is done automatically. The test script is normally written in coding language, making it different from the test plan.
Automated Interviewing With Coding Challenges
Unlike the , where the initial assessment is a phone screen, Amazon expands this assessment to sometimes include a coding challenge.
Some interviewers prefer this method, as the performance anxiety of interacting with another person is absent, and the only requirement on your end is to write code that executes correctly and efficiently.
This is also positive for Amazon, as they do not need to expend resources on conducting 30-45 minute interviews with candidates. Furthermore, they can also expand their reach substantially, as this process is somewhat automated.
Oftentimes, these coding challenges are driven through an engine similar to that of HackerRank, where your code is automatically analyzed for syntactic correctness, efficiency, and correctness for the task at hand. This gives a better signal to the interviewee about how well they are performing during the interview itself.
While all of these coding assessments will have instructions, they will often mimic those of HackerRank insofar as actually using the same submission and judging criteria.
Therefore, it is most likely a good idea to play around with the HackerRank interface, practicing a few problems to ensure that you do not get tripped up on the interface itself. This way, you can then just focus on solving the problem.

Kindly Explain What Code Inspection Is
Also known as code review, code inspection is a quality assurance process in which an inspector or a number of experts review and read parts of a source code to identify defects. It is normally done by trained individuals who peer-review work products following a well-laid down process. A person who conducts code inspection is an inspector, and as a general rule, the code inspector cannot approve a product if it has a defect. It is a necessary procedure that must be adhered to.
Describe The Jobs Responsibilities And Responsibilities

What Is The Use Of Selenium Grid And How It Works
Selenium Grid is used to execute the same or different test scripts on various platforms and browsers parallelly. This helps in testing the application in different environments concurrently and hence saving the execution time.
Working of Selenium Grid:Selenium Grid sent the tests to the hub. These tests are then redirected to Selenium Web Driver, which launch the browser and run the test.
What Is The Difference Between Assert And Verify Commands
Assert and Verify both are used to check whether the given condition is true or false.In Assert command, if any condition fails then the execution will stop, and no further test steps will be executed.
But in Verify command, if any condition fails then the execution will not stop and all further test steps will be executed.

What Is Object Repository
Object Repository is used to store all the objects that are used in the scripts in one or more centralized location rather than scattered all over the test script.
The main advantage of using Object repository is to segregate all objects in one place.
If any locator value of any web element changes, then changes need to be done at only one place i.e. object repository rather than making changes in all test cases where that particular locator is used.
Automate Beyond The Tests
While most SDETs mostly focus on automating tests, the great ones also use their skills to automate other tasks as well. They regularly seek out opportunities to make the software development process more efficient by eliminating the boring, repetitive tasks that distract humans from doing the really important and interesting things. Data generation, environment setup, and log parsing are all time-consumers that can be automated to assist with testing efforts.

Consider A Stack Of N Number Of Cards Which Are Piled Up And In Facing Down Each Card Has A Unique Number From The Range 1 To N The Card Is Stacked In Such A Way That It Exhibits The Following Behavior: Take The First Card And Put It Under The Stack Without Revealing Now The Next Card On The Top Will Have The Number 1 On It Next Take 2 Cards One After The Other And Put Is Under The Stack Without Revealing Yes You Guessed It Right
// Short and simple C++ algorithm#define N 10void compute // Make sure N elements are allocated{int j=0 for(int i=0 iLess
The algorithm used is:For each number n , we have to skip n places in the array. And then put number n at that position. The catch in the program is that we can skip only, not occupied places . Also, when we reach the end of the array, we have to move back to beginning of array Here, a variable ‘pos’ is used to store the final position of any element. Initially, pos is at 0. The skip takes the array, the current value of pos and the number of skips to be made.For example, for n=1, the values passed to skip would be: pos=0, n=1. This means that we have to skip 1 place starting from index 0.Similarly, for n=2, pos=1. This means we have to skip 2 places starting from index 1. Java Implementation:public class StackOfCards pos++ //if end of array is reached, take pos back to beginningif} // keep incrementing pos until a not occupied index is reached.whilereturn pos }}Less

What Are The Qualities That An Sdet Needs To Be Successful
There are several qualities that an SDET needs to be successful. They include excellent time management skills since timelines and deadlines have to be adhered to in product testing and development strong communication skills given that SDETs work with different teams and organizations and therefore need to relay information and network passion for designing since it is the SDETs main role, and lots of technical experience and expertise. A software design engineer in the test must also be hardworking and disciplined to meet the set deadlines and offered timelines and knowledgeable on software products.
What Is Exploratory And Ad Hoc Testing
- Exploratory Testing: Under this type of testing, the tester does not have knowledge of the requirements and they carry out the test simply on the basis of exploring the functionalities of an application. Exploratory testing is executed by domain experts.
- Ad hoc Testing: This type of testing fall under the category of informal testing. It is executed without any prior documentation or planning or adherence to any specific test design technique. They are conducted randomly when testers have good amount of knowledge about the Application Under Test . There are no expected results or business requirement document or test cases.

If The Proper Documentation For Testing Does Not Exist What Will You Do
There might be a situation wherein proper documentation is not available for test cases and still the tester is required to execute the test case. In such a situation, the tester might refer to some earlier mail provided by the client which describes all the requirements clearly. Additionally, he might also refer to the screenshots where the details of the changes are mentioned or any verbal communication with the client which would help to understand the exact functionality of the changes needed.
What Are The Professional Responsibilities Of A Sdet
This is yet another of the classic SDET Interview Questions. The roles and responsibilities of a SDET include:
- As a SDET Engineer: SDET happen to be involved in data design, product design as well as user interfaces
- As a customer spokesperson: SDET strive to understand the requirement for a product from the perspective of the customer and since they are involved at every stage of its development, till its final release they are the best advocate who can justify the need of the software
- Automation solutions: SDETs are required to build high quality and robust test automation solutions for performance, functional and regression testing
- Functional as well as non-functional testing: SDETs contribute to both functional as well as non-functional areas of testing. This means that they pay attention to functionality as well as other aspects as security of the application, absence of any hacks which might be misused and so on
- Important channel of communication: SDETs are responsible for investigating customer problems which are referred by the technical support team
- Designing: SDETs are also involved in architectural design discussions and help in providing effective feedback

Mention Some Of The Challenges You Faced In Your Former Roles How Did You Overcome Them
The main challenge that I faced in my former role was tight deadlines. I had less than a week to test even some of the most complicated software, given that our client base was highly demanding. This was a different work environment from my former workplace, and therefore I experienced a hard time at first. I had to adapt, work overtime, and collaborate with others to survive. However, I finally learned how to prioritize work and plan ahead for testing and development purposes.

Determine If Two Binary Trees Are Identical
This happens to be one of the typical SDET Interview Questions as part of the technical round.
As part of the problem statement, you will be provided with the roots of two binary trees. Identical trees happen to be those which have the same data and layout at each node. You should also remember that having the same data, doesnât necessarily make the trees identical. It is important to consider their structure as well.
The given problem can be addressed recursively. The base case of recursion for framing the solution for this is if two compared nodes are null or one of them is null.
Thus two trees are identical if:
- Data on their roots is same or both roots are null
- The left sub-tree of Y is identical to the left sub-tree of Z
- The right sub-tree of Y is identical to the right sub-tree of Z
You can proceed with simultaneously using depth-first traversal on both trees and then keep comparing the data at each level.
What Is The Main Challenge That You Foresee In This Job
I have dealt with several challenges in my career and can confidently say that they cut across regardless of the workplace. I do not, therefore, expect any specific challenge in this workplace. As for flexibility, I believe that I am highly flexible and will always be available if called upon. Anyway, I will be better positioned to identify any new challenges once I get this job since I will get the chance to experience the workplace.
