Basic Interview Questions

1. What are divergent and convergent thinking in project management?

Creative problem-solving processes depend on both convergent and divergent thinking. Convergent thinking is a logical, analytical process that focuses on related factors to come up with a feasible solution, while divergent thinking involves brainstorming around a problem without regard for feasibility.

2. How is divergent thinking different from creativity?

For tasks that involve logic and are not creative, such as answering multiple-choice tests, convergent thinking is the better choice. Divergent thinking, which is more creative, should be used in other instances.

3. How do you assess divergent thinking?

 Tests that measure divergent thinking usually assess multiple skills, and those most frequently assessed are fluency, flexibility, originality, and elaboration. There are many divergent thinking tests available. Some of them are considered general tests that can be administered to a broad segment of the population.

4. Could you name the main project aspects?

 Project management is a complex process made up of many interrelated aspects, including planning, organizing, and controlling. However, staffing and directing are also important. To provide these, a system of four factors is very important: know-how, practices, procedures, and technologies.

5. Why do we use the system lifecycle?

Replacing a faulty computer system with a more efficient one can be a difficult and time-consuming process, but software development managers can help make the transition go smoothly.

 Since 2008, ISO 26262 has covered functional safety standards for vehicles. It incorporates safety analysis methods that account for random and systematic errors in electrical and electronic systems, and it’s now broadly adopted worldwide. The automotive industry relies on software best practices outlined in ASPICE to reduce risk in connected cars.

14. Can you elaborate on the use of AUTOSAR?

  Automotive Open System Architecture (AUTOSAR) is an open, standardized software architecture for automotive manufacturers. It helps establish a common ECU software architecture for all AUTOSAR members and supports standardization in interfaces between application software and basic vehicular functions.

15. Why is the RTE necessary for AUTOSAR?

 The RTE provides the communication infrastructure that enables AUTOSAR software components to talk to each other, and it also serves as the means by which AUTOSAR software components access basic software modules, including the OS and communication service.

• Basic software architecture is layered
• Software code can be reused
• Transparency and distinct interfaces permit new business models

17. What is meant by the term ports in AUTOSAR?

The AUTOSAR Software Components use well-defined interfaces, called ports because they encapsulate the interfaces of a single component. A port represents a communication point between components and is mapped to a single component 

18. Is AUTOSAR an operating system?

 To support the dynamic deployment of customer applications and to provide an environment for those who require high-end computing power, the AUTOSAR Adaptive Platform is currently standardized by an operating system based on the POSIX standard.

22. Could you tell me what happens during static testing?

 Static testing is a software testing technique in which the program is examined for defects but not executed. It involves examining a program and its associated documents but not executing the code.

23. Why should we use static testing techniques?

• We can find and address defects and errors early on
• It improves development productivity
• It reduces testing costs and also the time for dynamic testing

23. Which technique is not used for static testing?

Static analysis is a software testing technique that involves analyzing code written by developers for structural defects, without running the code. Error guessing is not a static software testing technique.

24. How would you define what dynamic testing techniques are?

 Dynamic testing is a kind of software testing technique that analyzes the dynamic behavior of code. Dynamic testing can be performed after compiling and executing the program and analyzing parameters such as memory usage, CPU usage, response time, and overall performance.

25. What are the types of dynamic testing?

• Unit testing
• Integration testing
• System testing
• Acceptance testing
• Regression testing

26. What is the main difference between dynamic testing and static testing?

 Static and dynamic testing have different goals. Static testing is about preventing defects, while dynamic testing is about finding and fixing defects. Static testing verifies the program before compilation; dynamic testing validates it after compilation.

27. Is white box testing dynamic?

 White-box testing can be performed either dynamically, such as by security testers who have knowledge of the internal workings of the system, or statically, such as by using tools like AppScan, FxCop, and JavaCop.

28. What are static testing and structural testing?

 Structural testing is used to reveal errors that may have occurred in the programming of a program. It tests both results and processes, and it is sometimes referred to as white-box testing. Static testing does not require actual execution of the code; it simply involves examining the program as if it were already operating on a given platform.

29. Is functional testing dynamic?

 Dynamic Testing is a method used throughout the validation stage of software testing. It is performed by running the program and examining it for problems. Dynamic Testing includes both functional and non-functional tests.

30. What are the advantages of Dynamic Testing?
