Quality Analysis Interview Questions And Answers

A quality analyst makes sure company products and services remain of the highest quality at all times, in all stages of the production process.

To maintain product quality, analysts look at the current finished product and at the production process, from development to marketing. They put that in the context of the market and company goals and possibilities. They analyze this information for any problems and opportunities at improvement.

A Quality analyst develops ways to test a specific company's production process. He can also train other company personnel and any other quality inspectors to use this testing method.

A Quality analyst is highly trained, highly educated professional. It has outstanding analytical ability and extensive knowledge. It learns quickly and are able to expertly analyze current market demands and company-specific conditions. It is also very creative, because it solves problems by developing company-specific testing and improvement methods.

All quality analysts work with people. Analyzing the production process means analyzing the people working on production, as well as the technology involved. Quality analysts are able to interact effectively with employees at all levels of the production process. They also report to department and company managers and often personally meet clients or suppliers.

Quality analysts report to management and are able to make effective presentations of the situations or the problems, and the possible ways to fix problems.
They also interact with all levels of employees, clients, and suppliers and their written and verbal skills must be first rate to be effective.

A trace-ability matrix is used to cross check the test scripts per specified requirements of test cases.

Verification is based on verifying the functionality of a new system while validation is based on testing scenarios and specific cases of a new system.

Unit testing is the first test that is usually done by the developers.

Provide lists of software such as: SAS and SWOT Manager or any software and automated testing emulation system which you have used. You may also clarify the differences between them, and explain how these tools enhance reliability.

Bug is a deviation from the expected result that can be fixed and solved.

Defect is a problem in the application algorithm or the mechanism that leads to consistent failure or an error that requires a massive change.

R & R stands for reproducibility and repeatability. It is a system measurement error that determines the percentage of error, the type of error and its affects on the system.

Bug life cycle consists of several statuses of an error during its life cycle such as: open, deferred, rejected, solved, fixed, reopen, and closed. You can talk about the process flow and how you monitor and determine the status at various points.

If yes, describe the goals of the audit, how you have monitored the audit findings and how you have controlled the corrective actions.

Clarify in a specific and brief manner how you determine the timing for system testing and what to test. Like:
What point do you finalize the testing at?

Quality assurance refers to the planned and systematic way of monitoring the quality of process which is followed to produce a quality product. Quality assurance tracks the outcomes and adjusts the process to meet the expectation.

Concern with the quality of the product. Quality control finds the defects and suggests improvements. The process set by quality assurance is implemented by quality control. The quality control is the responsibility of the tester.

Software testing is the process of ensuring that product which is developed by the developer meets the user requirement. The motive to perform testing is to find the bugs and make sure that they get fixed.

A good time to start the quality assurance is from the beginning of the project start-up. This will lead to plan the process which will make sure that product coming out meets the customer quality expectation. Quality assurance also plays a major role in the communication between teams. It gives time to step up the testing environment. The testing phase starts after the test plans are written, reviewed and approved.

The difference between smoke and sanity testing is described below:
★ Sanity testing is performed when new build is released after fixing bugs where as smoke testing is performed to check the major functions of the application.
Sanity is performed by the tester or the developer but smoke testing can be performed by the tester or developer.
★ Smoke testing is performed earlier where as sanity is performed after the smoke testing.
Sanity testing is narrow and deep approach of testing and smoke testing is focused testing based on major functions.

Destructive testing includes methods where material is broken down to evaluate the mechanical properties, such as strength, toughness and hardness.
For example, finding the quality of a weld is good enough to withstand extreme pressure and also to verify the properties of a material.

Benefits of destructive Testing (DT):
Verifies properties of a material
Determines quality of welds
Helps you to reduce failures, accidents and costs
Ensures compliance with regulations

The test-ware is:
★ The subset of software which helps in performing the testing of application.
★ Test-ware are required to plan, design, and execute tests. It contains documents, scripts, inputs, expected results, set-up and additional software or utilities used in testing.
★ Test-ware is term given to combination of all utilities and application software that required for testing a software package.

Test-ware is special because it has:
1) Different purpose
2) Different metrics for quality and
3) Different users

The difference between Retesting and Regression testing are below:
★ Retesting is done to verify defects fixes where as regression is perform to check if the defect fix have not impacted other functionality that was working fine before doing changes in the code.
★ Retesting is planned testing based on the defect fixes listed where as regression is not be always specific to any defect fix. Also regression can be executed for some modules or all modules.
★ Retesting concern with executing those test cases that are failed earlier whereas regression concern with executing test cases that was passed in earlier builds.
★ Retesting has higher priority over regression, but in some case retesting and regression testing are carried out in parallel.

Priority of bug concerns with application from the business point of view.
Like:
How quickly we need to fix the bug?
How soon the bug should get fixed?
