Interview Questions

QA stands for QUALITY ASSURANCE. QA team assures the quality by monitor the whole development process. QA tracks the outcomes and adjusting process to meet the expectation.

The role of Quality Assurance is discussed below:

- QA team is responsible for monitoring the process to be carried out for development.

- Responsibilities of QA team are planning testing execution process.

- QA Lead creates the time tables and agrees on a Quality Assurance plan for the product.

- QA team communicated QA process to the team members.

- QA team ensures traceability of test cases to requirements.

Stack. Because of its LIFO (Last In First Out) property it remembers its ‘caller’ so knows whom to return when the function has to return. Recursion makes use of system stack for storing the return addresses of the function calls. Every recursive function has its equivalent iterative (non-recursive) function. Even when such equivalent iterative procedures are written, explicit stack is to be used.

Tips :

Occasionally some things go out of control of leaders such as the suitable skill pool in the organization, deadline, and the economic situation. The failure can happen if the employees are unconcerned and negative. In leadership interview questions, the interviewer wants to know your way in resolving the difficult situations, so you should concentrate on analyzing the failure and draw the experience from it. The way you used the difficulties to design the policies and trainings. Show your bravery to face with the failure and ready to recover and continue going on.

Tips :

Leaders develop ownership by involving employees in the decision-making and planning process. They provide resources to facilitate employee success and empower employees by devolving authority to get things done efficiently. Effective leaders develop processes that engage employees in achieving the strategic vision. 

A system call is a function.subroutine which interrupts the currently executing program and transfers control to the interrupt routine.The contents of the executing program are saved and after the interrupt routine finishes its function,control is transferred back to the executing program. If we talk in the context of Linux then System calls are called kernel mode.

Whereas API (Application Programming Interface) is a function or a set of functions, objects, protocols or data-structures for the support of application development for developers/programmers. It is actually a kind of function definition which specifies how to make available of a specific service of the system/OS to the other program/process or system.

Flow control, also called optimized production technology, focuses on the efficient flow of material through the production process. The philosophy of flow control focuses on bottlenecks. For example, an owner using flow control will not buy a machine capable of 1,000 units an hour if supply 500 units. Examine systems and determine where lowest flow is experienced, then address that point and make sure it operates at full capacity. Flow control applies well where maximum productivity is required.
