Your interviewer is looking for strong management skills. You need to be creative and describe your toughest management task, even if it doesn't meet all the criteria. Most situations don't. Organisational and interpersonal skills, handling pressure and good handling of this question are indicative of effective management skills.

I can manage all the resource based on my knowledge and skills. It will provide better results as well as team building and time management

C Software Developer/ Programmer

Ques:- Overloading?? How many types? explain each type

Asked In :-

Right Answer:
Overloading refers to the ability to define multiple functions or operators with the same name but different parameters. There are two main types of overloading:

1. **Function Overloading**: This allows multiple functions to have the same name but differ in the type or number of their parameters. The compiler determines which function to call based on the arguments passed.

2. **Operator Overloading**: This allows developers to redefine the way operators work for user-defined types (like classes). It enables operators to perform operations on objects of those types, similar to how they work with built-in types.

Ques:- Implicity? Why we use in C++? Write programme??

Asked In :-

Right Answer:
Implicitly in C++ refers to automatic type conversion that the compiler performs when it converts one data type to another without explicit instruction from the programmer. This is often used to promote smaller data types to larger ones to avoid data loss.

Here’s a simple program demonstrating implicit conversion:

```cpp
#include <iostream>
using namespace std;

int main() {
int intVar = 10;
double doubleVar = intVar; // Implicit conversion from int to double

cout << "Integer value: " << intVar << endl;
cout << "Converted double value: " << doubleVar << endl;

return 0;
}
```

Ques:- Polymorpishm? Write an example programme?

Asked In :-

Right Answer:
Polymorphism is a feature in programming that allows methods to do different things based on the object that it is acting upon. In C, polymorphism can be achieved using function pointers or structures.

Here is an example program demonstrating polymorphism using function pointers:

```c
#include <stdio.h>

// Function prototypes
void drawCircle();
void drawSquare();

// Function pointer type
typedef void (*ShapeFunction)();

int main() {
// Array of function pointers
ShapeFunction shapes[2];

// Assign functions to the array
shapes[0] = drawCircle;
shapes[1] = drawSquare;

// Call the functions
for (int i = 0; i < 2; i++) {
shapes[i](); // Calls the appropriate function
}

return 0;
}

void drawCircle() {
printf("Drawing a Circlen");
}

void drawSquare() {
printf("Drawing a Squaren");
}
```

Ques:- Explicity? Difference between implicity? what is the advantage

Asked In :-

Right Answer:
Explicit type conversion (casting) is when you manually convert one data type to another, using specific syntax (e.g., `(int)3.14` converts a float to an integer). Implicit type conversion (automatic type conversion) occurs when the compiler automatically converts one data type to another without explicit instruction (e.g., assigning an integer to a float variable).

The advantage of explicit conversion is that it gives you control over the conversion process, ensuring that you handle data types as intended. Implicit conversion is convenient and reduces code verbosity, but it can lead to unintended data loss or errors if not carefully managed.

Ques:- What is LINQ and can you explain same with example?

Asked In :-

Right Answer:
LINQ (Language Integrated Query) is a feature in .NET that allows you to query collections of data in a more readable and concise way using C# or VB.NET syntax. It enables querying of various data sources like arrays, collections, databases, XML, etc.

Example:

```csharp
using System;
using System.Collections.Generic;
using System.Linq;

class Program
{
static void Main()
{
List<int> numbers = new List<int> { 1, 2, 3, 4, 5 };
var evenNumbers = from num in numbers
where num % 2 == 0
select num;

foreach (var num in evenNumbers)
{
Console.WriteLine(num);
}
}
}
```

In this example, LINQ is used to filter even numbers from a list.

JAVA Software Developer/ Programmer

Ques:- Java (keywords explanation like static, final, finally),exception handling, inheritance

Asked In :-

Right Answer:
- **static**: A keyword used to indicate that a member (variable or method) belongs to the class rather than instances of the class. It can be accessed without creating an object of the class.

- **final**: A keyword used to declare constants, prevent method overriding, and prevent inheritance of classes. Once a variable is declared as final, its value cannot be changed.

- **finally**: A block used in exception handling that follows a try-catch block. It always executes regardless of whether an exception was thrown or caught, typically used for cleanup code.

- **Exception Handling**: A mechanism to handle runtime errors, allowing the program to continue execution. It uses try, catch, and finally blocks to manage exceptions.

- **Inheritance**: A fundamental OOP concept where a new class (subclass) inherits properties and behaviors (methods) from an existing class (superclass), promoting code reusability and establishing a hierarchical relationship.

Comments

DK BOSS Jul 21, 2021

Final is used to apply restrictions on class, method and variable. Final class can't be inherited, final method can't be overridden and final variable value can't be changed. Finally is used to place important code, it will be executed whether exception is handled or not.

Data Structure Software Developer/ Programmer

Ques:- Database queries and normal forms

Asked In :- ESDS Software Solution, vardhman textiles, trifacta, ttec,

Right Answer:
Database queries are requests for data from a database, typically written in SQL. Normal forms are guidelines for structuring a relational database to reduce redundancy and improve data integrity. The main normal forms are:

1. **First Normal Form (1NF)**: Ensures that all columns contain atomic values and each entry in a column is of the same type.
2. **Second Normal Form (2NF)**: Requires that all non-key attributes are fully functionally dependent on the primary key.
3. **Third Normal Form (3NF)**: Ensures that all attributes are only dependent on the primary key and not on other non-key attributes.

There are higher normal forms (BCNF, 4NF, 5NF) that address more complex types of redundancy.
