Sandberg Translation Partners Interview Questions and Answers
Q1. Tell me about abstraction and interfaces
Abstraction is the concept of hiding complex implementation details and showing only the necessary features. Interfaces define a contract for classes to implement.
Abstraction allows us to focus on what an object does rather than how it does it
Interfaces define a set of methods that a class must implement, without specifying how they are implemented
Abstraction and interfaces help in achieving loose coupling and flexibility in software design

Q2. What is mentioned bypolymorphism
Polymorphism is the ability of a single function or method to operate on different types of data.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).
Example: Inheritance in object-oriented programming languages like Java allows for polymorphism.
Example: A method 'draw()' can be implemented differently in various subclasses of a 'S...read more

Q5. Cut one cake into 8 pieces with 3 slices
Cut the cake into 8 pieces by making 3 slices, creating 8 equal-sized slices.
Make two vertical cuts to divide the cake into 4 equal quarters.
Then make one horizontal cut through the middle of the cake to create 8 equal-sized slices.
Each slice will be a triangular piece of cake.
Q6. Why OOPs is used
OOP is used for organizing code into reusable objects, promoting code reusability, modularity, and easier maintenance.
Encapsulation: Data and methods are bundled together in objects, promoting data security and code organization.
Inheritance: Allows for the creation of new classes based on existing ones, promoting code reuse and reducing redundancy.
Polymorphism: Objects can be treated as instances of their parent class, allowing for flexibility and extensibility.
Modularity: Co...read more
Q7. Array lists vs arrays
Array lists are dynamic in size, while arrays have fixed sizes.
Array lists can grow or shrink in size dynamically, while arrays have a fixed size.
Array lists are implemented using dynamic arrays, while arrays are static data structures.
Array lists provide methods for adding, removing, and accessing elements easily, while arrays require manual resizing and shifting of elements.
Example: ArrayList<String> vs String[]
Q8. Flexible with moving
I am open to relocating for the right opportunity.
I am willing to move to different locations for career growth
I understand the importance of being flexible with relocation for job opportunities
I have experience moving for previous job opportunities, such as relocating for internships or projects
Q9. Divisible by 2 code
Write a code to check if a number is divisible by 2.
Use the modulo operator (%) to check if the remainder is 0 when divided by 2.
If the remainder is 0, then the number is divisible by 2.
Example: if(num % 2 == 0) { // divisible by 2 }
