Round duration - 90 minutes
Round difficulty - Medium
Given an array arr
consisting of 'N' distinct integers, your task is to generate all possible non-empty subsets of the given array.
You can return the subsets in any order.
The ...
Generate all possible non-empty subsets of a given array of distinct integers.
Use recursion to generate all subsets by including or excluding each element in the array.
Maintain a current subset and iterate through the array to generate subsets.
Print each subset as it is generated to get all possible non-empty subsets.

Reversed link...
Reverse a singly linked list of integers and return the head of the reversed linked list.
Iterate through the linked list and reverse the pointers to point to the previous node instead of the next node.
Keep track of the current, previous, and next nodes while traversing the linked list.
Update the head of the reversed linked list to be the last node encountered.
Ensure to handle edge cases like an empty linked list or a s...

Tip 1 : Maintain a clean resume and have in-depth knowledge of the projects, as in the technical round the interviewer mainly asks technical questions regarding the projects. Questions based on projects are predictable and answering them can give a good impression during the interview.
Tip 2 : Be clear in explaining the approach to coding questions.
Tip 3 : Admit it, if you are not confident in a particular topic. Accepting your weakness is better than a wrong answer.
Tip 1 : Use formal resume templates and maintain a neat resume.
Tip 2 : Have few development projects on the resume with brief summary of the skills implemented.
Tip 3 : Mention your skills in proper sub-sections.

Oops stands for Object-Oriented Programming. It is a programming paradigm that uses objects to represent real-world entities.
Advantages: code reusability, modularity, encapsulation, inheritance, polymorphism
Disadvantages: complexity, steep learning curve, performance overhead
Example: creating a class 'Car' with properties like 'make', 'model', and 'year', and methods like 'start_engine' and 'stop_engine'
I applied via Company Website and was interviewed before Oct 2019. There were 4 interview rounds.
I applied via Campus Placement and was interviewed before Nov 2021. There were 3 interview rounds.

This was a technical round with questions on DBMS.
Data integrity refers to the accuracy, consistency, and reliability of data throughout its lifecycle.
Data integrity ensures that data is accurate and consistent in storage and transmission.
It involves maintaining the quality and reliability of data over time.
Methods for ensuring data integrity include checksums, encryption, and error detection codes.
Examples of data integrity violations include data corruption, unautho...
A trigger is a special type of stored procedure that automatically executes when certain events occur in a database.
Triggers are used to enforce business rules, maintain data integrity, and automate repetitive tasks.
They can be triggered by INSERT, UPDATE, or DELETE operations on a table.
Examples of triggers include auditing changes to a table, updating related tables when a record is modified, or enforcing referential...
Clustered indexes physically order the data in the table, while non-clustered indexes do not.
Clustered indexes determine the physical order of data in the table, while non-clustered indexes do not.
A table can have only one clustered index, but multiple non-clustered indexes.
Clustered indexes are faster for retrieval of data, especially range queries, compared to non-clustered indexes.
Non-clustered indexes are stored se...

Technical interview round with questions on DBMS.
UNION combines and removes duplicates, UNION ALL combines without removing duplicates.
UNION merges the result sets of two or more SELECT statements and removes duplicates.
UNION ALL merges the result sets of two or more SELECT statements without removing duplicates.
UNION is slower than UNION ALL as it involves removing duplicates.
Example: SELECT column1 FROM table1 UNION SELECT column1 FROM table2;
Example: SELECT column...
A cursor in PL/SQL is used to retrieve and process multiple rows of data one at a time.
Allows iteration over a result set
Retrieves data row by row
Can be used to update or delete rows in a table

This was a managerial round with typical behavioral problems.
Tip 1 : Since this was a SQL post, I would suggest you to get the basics intact and try practicing few queries.
Tip 2 : Must do Previously asked Interview as well as Online Test Questions.
Tip 3 : Go through all the previous interview experiences from Codestudio and Leetcode.
Tip 1 : Have at-least 2 good projects explained in short with all important points covered.
Tip 2 : Every skill must be mentioned.
Tip 3 : Focus on skills, projects and experiences more.

I applied via Naukri.com and was interviewed before Oct 2019. There was 1 interview round.
A generic swap function swaps two values of any data type.
The function should take two parameters of any data type.
Use a temporary variable to store the value of one parameter.
Assign the value of the second parameter to the first parameter.
Assign the value of the temporary variable to the second parameter.

Creating test cases for random scenarios ensures software reliability and robustness through diverse input validation.
Identify edge cases: Test with minimum and maximum input values, e.g., an empty array vs. a large array.
Use random data: Generate random inputs to simulate real-world usage, e.g., random user names or passwords.
Test invalid inputs: Ensure the system handles unexpected inputs gracefully, e.g., negative n...
