GAVS Technologies Interview Questions, Process, and Tips

SLA of incidents p1, p2, p3, p4 varies based on severity and impact.

• SLA for p1 incidents is typically shorter as they are critical and require immediate attention.

• SLA for p2 incidents is longer than p1 but still requires prompt resolution.

• SLA for p3 incidents is moderate as they are less critical and can be resolved within a reasonable timeframe.

• SLA for p4 incidents is the longest as they are minor issues with low impa

Dependency injection is a design pattern where components are given their dependencies rather than creating them internally.

• Allows for easier testing by mocking dependencies

• Promotes loose coupling between components

• Improves code reusability and maintainability

• Example: Constructor injection, Setter injection

Rendering variant refers to different ways in which a software application can display content or user interface elements.

• Rendering variant can include different layouts, themes, colors, fonts, and styles for displaying content.

• It allows users to customize the appearance of the application to suit their preferences.

LSP is a principle of SOLID design that states that objects of a superclass should be replaceable with objects of its subclasses.

• LSP stands for Liskov Substitution Principle

• It ensures that the behavior of the program remains consistent when a subclass is used in place of its superclass

• Violating LSP can lead to unexpected behavior and bugs

• Example: If a program expects a Bird object, it should be able to use any subclass

Angular life cycle is a series of events that occur from the creation of a component to its destruction.

• ngOnChanges - called when an input property changes

• ngOnInit - called once after the first ngOnChanges

• ngDoCheck - called during every change detection cycle

• ngAfterContentInit - called after content is projected into component

• ngAfterContentChecked - called after every check of projected content

• ngAfterViewInit - called ...read more
