Essential Interview Questions For Design Engineer
1. What are the key principles of solid design patterns?
Solid design patterns are a set of principles used to create software that is maintainable, flexible, and extensible. The five key principles are:
- Single responsibility principle: Each class should have a single, well-defined responsibility.
- Open-closed principle: Classes should be open for extension but closed for modification.
- Liskov substitution principle: Derived classes must be substitutable for their base classes.
- Interface segregation principle: Clients should not be forced to depend on interfaces they do not use.
- Dependency inversion principle: High-level modules should not depend on low-level modules. Both should depend on abstractions.
2. Explain the difference between cohesion and coupling.
Cohesion
- Cohesion refers to the degree to which the elements of a module are related to each other.
- High cohesion means that the elements are closely related and work together to achieve a specific goal.
- Low cohesion means that the elements are loosely related and do not work together well.
Coupling
- Coupling refers to the degree to which modules depend on each other.
- High coupling means that modules are tightly coupled and depend on each other for their functionality.
- Low coupling means that modules are loosely coupled and do not depend on each other for their functionality.
3. Describe the process of requirements gathering and analysis.
Requirements gathering and analysis is the process of gathering and understanding the needs of the stakeholders in order to develop a software system that meets those needs. The process typically involves the following steps:
