Relational databases store data in structured tables, allowing for complex queries and relationships between data entities.
Data is organized in tables (e.g., Customers, Orders) with rows and columns.
Each table has a primary key that uniquely identifies each record (e.g., CustomerID).
Tables can be related through foreign keys, enabling data integrity (e.g., Order table referencing CustomerID).
SQL (Structured Query ...
Smoke testing checks basic functionality, while sanity testing verifies specific functionalities after changes. Both are part of regression testing.
Smoke Testing: A preliminary test to check if the basic functions of an application work. Example: Verifying if the application launches.
Sanity Testing: A focused test to ensure that specific functionalities work after changes. Example: Testing a new feature after a bu...
IMAP (Internet Message Access Protocol) is a protocol for accessing and managing email on a remote mail server.
IMAP allows users to access their email from multiple devices while keeping messages synchronized.

IMAP supports folder management, allowing users to organize emails into different folders.
Example: A user can read an email on their pho...
A VBA program can filter Excel data based on two columns and transfer the results to another sheet efficiently.
Use the AutoFilter method to filter data based on criteria from two columns.
Example: Filter Column A for 'Sales' and Column B for '2023'.
Copy the visible filtered data to a new sheet using the Range.Copy method.
Ensure to clear previous data in the destination sheet before copying new data.

- Q1. What is a friend function
- Ans.
A friend function is a non-member function that has access to the private and protected members of a class.
Declared inside the class but defined outside the class scope
Can access private and protected members of the class
Not a member of the class but has access to its private members
Used to allow external functions to access and modify private data of a class
Can be declared as a friend in another class
- Q2. Some VI editor commands
- Q3. Definition of atoi function of C
- Ans.
atoi function converts a string to an integer in C.
The function takes a string as input and returns an integer.
Leading white spaces are ignored.
If the string contains non-numeric characters, the function stops conversion and returns the converted value.
The function returns 0 if the input string is not a valid integer.
Example: atoi('123') returns 123.
- Q4. A program to print star pattern
- Ans.
A program to print star pattern
Use nested loops to print the pattern
The outer loop controls the number of rows
The inner loop controls the number of stars to be printed in each row
Use print() or println() function to print the stars
- Q5. Run time polymorphism in C++
- Ans.
Run time polymorphism is the ability of a program to determine the object type at runtime and call the appropriate method.
It is achieved through virtual functions and dynamic binding.
Allows for more flexible and extensible code.
Example: a base class Animal with virtual function makeSound() and derived classes Dog and Cat that override makeSound().
At runtime, if an Animal pointer points to a Dog object, calling makeSoun...
- Q6. Some queries like finding the second highest salary in a table
- Ans.
To find the second highest salary, we can use SQL queries with various approaches like subqueries or the DISTINCT keyword.
Use a subquery: SELECT MAX(salary) FROM employees WHERE salary < (SELECT MAX(salary) FROM employees);
Use DISTINCT: SELECT DISTINCT salary FROM employees ORDER BY salary DESC LIMIT 1 OFFSET 1;
Use ROW_NUMBER(): SELECT salary FROM (SELECT salary, ROW_NUMBER() OVER (ORDER BY salary DESC) AS rank FROM...
- Q7. What is right outer join and it's use in real world scenario
- Ans.
Right outer join is a type of join operation that returns all the rows from the right table and the matching rows from the left table.
Right outer join is denoted by the RIGHT JOIN keyword in SQL.
It is used to combine rows from two tables based on a related column.
In the result set, unmatched rows from the right table will have NULL values for the columns of the left table.
A real-world scenario for using a right outer j...
- Q8. What is refrential integrity
- Q9. Difference between Primary key and Unique key
- Ans.
Primary key uniquely identifies a record in a table, while Unique key ensures uniqueness of a column.
Primary key can't have null values, Unique key can have one null value
A table can have only one Primary key, but multiple Unique keys
Primary key is automatically indexed, Unique key is not necessarily indexed
- Q10. Triggers and their types
- Ans.
Triggers are database objects that are automatically executed in response to certain events.
Triggers can be used to enforce business rules, audit changes, or replicate data.
There are two types of triggers: DML triggers and DDL triggers.
DML triggers are fired in response to DML statements (INSERT, UPDATE, DELETE).
DDL triggers are fired in response to DDL statements (CREATE, ALTER, DROP).
- Q11. Swap two character variables without using third
- Ans.
Swapping two character variables without using third
Use XOR operator to swap two variables without using third variable
Assign the XOR of both variables to the first variable

Interview Preparation Tips
Experience: Questions are easy but time is main constraint, try to complete each section with at least 80% accuracy.
Round: Technical Interview
Experience: Questions were mainly on C,C++(OOPS concepts) and Unix. If you don't know the answer of some of the questions just tell them don't try to give random answers. Be well prepared with your OOPs concepts as that will play crucial part in clearing the technical round.
Tips: Be positive and confident. If you know the answer or you can try then only answer otherwise just say sorry.
Round: HR Interview
Experience: HR round was more like a formality. The HR was asking same set of questions from everyone and all four who got into HR round got selected.

- Q2. What is the internal working mechanism of a HashMap?
- Ans.
HashMap is a data structure that stores key-value pairs and uses hashing to quickly retrieve values based on keys.
HashMap internally uses an array of linked lists to store key-value pairs.
When a key-value pair is added, the key is hashed to determine the index in the array where the pair will be stored.
If multiple keys hash to the same index (collision), a linked list is used to store these pairs.
To retrieve a value, t...
