I do know english well and use it daily to communicate, but the moment I'm in an interview, I just get stuck. since it's not my first language, I struggle to express what I actually feel. I know the answer in my head, but I just can’t deliver it properly at that moment. Please guide me

    • Use Stream API: Convert the list of employees to a stream using `stream()` method.

    • Map to Employee Type: Use `map()` to transform the employee objects to their types (e.g., `employee.getType()`).

    • Distinct Values: Apply `distinct()` to filter out duplicate types.

    • Collect Results: Use `collect(Collectors.toSet())...

    Design an Employee class and an abstract class to represent different employee types in a software application.

    • Create an abstract class 'Employee' with common attributes like name and ID.

    • Define abstract methods like 'calculateSalary()' that subclasses must implement.

    • Implement concrete classes like 'FullTimeEmployee' and 'PartTimeEmployee' that extend 'Employee'.

  • Ans. 

    The problem involves dividing an array into K subsets with equal sum.

    • Use backtracking to try all possible combinations of subsets.

    • Keep track of the sum of elements in each subset and check if they are equal to the target sum.

    Sort a doubly linked list where each node's position deviates at most K positions from its position in the sorted list.

    • Iterate through the doubly linked list and maintain a min-heap of size K+1 to keep track of the next smallest element.

    • Remove the smallest element from the heap and add it to the sorted list. Update the heap with the next element from the removed node's next position.

  • Ans. 

    Find root values of duplicate subtrees in a binary tree.

    • Traverse the tree in a bottom-up manner to identify duplicate subtrees.

    • Use a hashmap to store the subtree structures and their frequencies.

    • Return the root values of duplicate subtrees based on hashmap entries.

Round 2 - Telephonic Call 

(1 Question)

Round duration - 25 minutes
Round difficulty - Medium

The technical Interview round was not at all difficult. The main focus of the interviewer was my projects and development fields.
He also asked some DS/Algo questions that were at a medium level, and some easy questions for database management.

  • Q1. Can you explain the concept of keys in database management systems?
  • Ans. 

    Keys in database management systems are unique identifiers for rows in a table.

    • Keys ensure data integrity by enforcing uniqueness and relationships between tables.

    • Primary key uniquely identifies each record in a table (e.g. employee ID).

    • Foreign key establishes a link between two tables by referencing the primary key of another table.
