- Q1. Questions on microservices
- Q2. Advanced features of java
- Ans.
Advanced features of Java include lambda expressions, streams, functional interfaces, and modules.
Lambda expressions allow for functional programming in Java.
Streams provide a way to process collections of objects in a functional style.
Functional interfaces are interfaces with a single abstract method, used for lambda expressions.
Modules allow for modular programming in Java, improving code organization and reusability
- Q3. Features in Java 11 and beyond
- Ans.
Java 11 introduced new features like local-variable syntax for lambda parameters, HTTP client API, and more.
Local-variable syntax for lambda parameters allows var to be used in lambda expressions.

Interview Preparation Tips
Experience: Round 1: Online objective test.
There were questions from Operating Systems, C, Algorithms, Data Structures.
Round 2: Online and subjective (choose language C++ or JAVA). This round had 15 questions.
Data structures, C++ questions, Fibonacci optimisation, algorithms (DFS/BFS).
Round: Technical Interview
Experience: In the first round of interview they asked me questions about :1) My project (asked no. of classes and mention their responsibilities).
2) ACID properties of database and indexing in a database.
There were also questions related to OOPS concepts including polymorphism, composition, aggregation, inheritance, Abstract classes, interface; difference between usage of abstract class and interface, can abstract class be instantiated, how to access child class methods having reference of base class.
There was another question on run time and compile time binding and under which category do we classify method overloading and also questions on code for deleting the duplicate nodes in a sorted link list and printing root to leaf paths in a binary search tree.
Round: Technical Interview
Experience: This was the second round of the interview. They asked me the following questions,There is a tree (not binary) and all non-leaf nodes are RED in colour. Some leaf nodes are white in colour. If a node has all white coloured children then its colour can be changed into white. So we have to convert maximum number of nodes into white colour – write program for the same.
Code for checking whether a given binary tree balanced or not.
What are virtual functions, what is their role?
Questions related to virtual functions.
You are given the details of each transaction of each item i.e. item_name, quantity, price. So at the end of the day, you want top 50 items that have been sold. There are two cases:
In the first case you have fixed number of items.
In the second case very large number of items – so you need to decide what data structure to be used for this.
Round: Technical Interview
Experience: In the third round of the interview they asked questions like :
1) Types of tree traversals (breadth first and depth first (pre, post, in)
2) Determining width of binary tree i.e. using breadth wise traversal
3) Why files are preferred over databases?

- Q4. Code for deleting the duplicate nodes in a sorted link list?
- Ans.
Code to delete duplicate nodes in a sorted linked list
Traverse the linked list and compare adjacent nodes
If nodes are equal, delete one of them
Repeat until all duplicates are removed
- Q5. Printing root to leaf paths in a binary search tree
- Ans.
Printing all root to leaf paths in a binary search tree
Traverse the tree recursively and keep track of the current path
When a leaf node is reached, add the current path to the list of paths
Print all the paths in the list
Use an array of strings to store the paths
- Q6. Given an Array of Integers, Find two elements in the array whose sum is closest to zero?
- Ans.
Find two integers in an array whose sum is closest to zero.
Sort the array in ascending order.
Initialize two pointers at the beginning and end of the array.
Move the pointers towards each other until the sum is closest to zero.
- Q7. What are virtual functions, what is their role? Questions related to virtual functions?

- Q9. How do you quickly count the number of set bits in a 32-bit integer in linear time (with respect to the number of set bits)?
- Ans.
Count set bits in a 32-bit integer in linear time
Use bit manipulation to count set bits
Divide the integer into 16-bit chunks and count set bits in each chunk
Use lookup tables to count set bits in each 8-bit chunk
Use parallel processing to count set bits in multiple integers simultaneously
- Q10. Determining width of binary tree i.e. using breadth wise traversal
- Ans.
To determine the width of a binary tree using breadth-wise traversal, we need to count the number of nodes at each level.
Perform a breadth-first traversal of the binary tree
Count the number of nodes at each level
Keep track of the maximum number of nodes seen at any level
Return the maximum number of nodes seen
- Q11. Why files are preferred over databases?
- Ans.
Files are preferred over databases for certain types of data and applications.
Files are faster for small amounts of data.
Files are easier to manage and backup.
Files are more flexible for certain types of data, such as images or videos.
Databases are better for complex data relationships and queries.
Databases are more secure and scalable for large amounts of data.
The choice between files and databases depends on the spec
