- Q2. What is the purpose DNS?
- Ans.
DNS stands for Domain Name System and its purpose is to translate domain names into IP addresses.
DNS helps users easily access websites by translating human-readable domain names (e.g. www.google.com) into machine-readable IP addresses (e.g. 172.217.3.206).
It helps in load balancing by distributing traffic among multiple servers based on the IP address resolved by DNS.
DNS also provides redundancy and fault tolerance by...
- Q3. What is CIA Triad
- Ans.
CIA Triad is a foundational concept in cybersecurity that stands for Confidentiality, Integrity, and Availability.
Confidentiality ensures that data is only accessible to authorized individuals.
Integrity ensures that data is accurate and has not been tampered with.
Availability ensures that data is accessible when needed, without interruption.
Examples: Encrypting sensitive information for confidentiality, using checksums...
- Q4. Encryption and hashing
- Q5. Encryption and decryption comes under which part of the CIA triad.
- Ans.
Encryption and decryption come under the confidentiality part of the CIA triad.
Encryption and decryption are used to protect sensitive information from unauthorized access.
Confidentiality ensures that only authorized users can access the data.
Examples of encryption methods include AES, RSA, and DES.

- Q1. What is firewall?
- Ans.
A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
Acts as a barrier between a trusted internal network and untrusted external network
Filters network traffic based on rules set by the administrator
Can be hardware-based or software-based
Examples include Cisco ASA, Palo Alto Networks, and pfSense
- Q2. Difference between IDS and IPS
- Ans.
IDS detects and logs potential security threats, while IPS actively blocks and prevents them.
IDS stands for Intrusion Detection System, which monitors network traffic for suspicious activity and alerts the administrator.
IPS stands for Intrusion Prevention System, which not only detects threats like IDS but also takes action to block or prevent them.
IDS is passive in nature, while IPS is active and can automatically res...
- Q3. Showed me a log and asked about what happened in the log?
- Q4. What is write blocker
- Ans.
A write blocker is a hardware device or software tool that prevents data from being written to a storage device.
Used in digital forensics to prevent accidental or intentional modification of data during analysis
Ensures the integrity of evidence by allowing read-only access to the storage device
Commonly used in investigations involving computers, mobile devices, and other digital media
Examples include Tableau write bloc

- Q1. Implement Merge Sort.
- Ans.
Merge Sort is a divide and conquer algorithm that sorts an array by dividing it into two halves, sorting them separately, and then merging the sorted halves.
Divide the array into two halves
Recursively sort the two halves
Merge the sorted halves
- Q2. Given a BST containing distinct integers, and a number ‘X’, find all pairs of integers in the BST whose sum is equal to ‘X’.
- Ans.
Find pairs of integers in a BST whose sum is equal to a given number.
Traverse the BST and store the values in a hash set.
For each node, check if (X - node.value) exists in the hash set.
If yes, add the pair (node.value, X - node.value) to the result.
Continue traversal until all nodes are processed.
- Q3. Given a set of time intervals in any order, merge all overlapping intervals into one and output the result which should have only mutually exclusive intervals.
- Ans.
Merge overlapping time intervals into mutually exclusive intervals.
Sort the intervals based on their start time.
Iterate through the intervals and merge overlapping intervals.
Output the mutually exclusive intervals.
Example: [(1,3), (2,6), (8,10), (15,18)] -> [(1,6), (8,10), (15,18)]
- Q4. What are the different types of hashing? Suggest an alternative and a better way for Linear Chaining.
- Ans.
Different types of hashing and alternative for Linear Chaining
Different types of hashing include division, multiplication, and universal hashing
Alternative for Linear Chaining is Open Addressing
Open Addressing includes Linear Probing, Quadratic Probing, and Double Hashing
- Q5. Implement AVL Tree.
- Ans.
An AVL tree is a self-balancing binary search tree where the heights of the left and right subtrees differ by at most one.
AVL tree is a binary search tree with additional balance factor for each node.
The balance factor is the difference between the heights of the left and right subtrees.
Insertion and deletion operations in AVL tree maintain the balance factor to ensure the tree remains balanced.
Rotations are performed ...
- Q6. Minimum number of squares whose sum equals to given number n.
- Ans.
Find the minimum number of squares whose sum equals to a given number n.
Use dynamic programming to solve the problem efficiently.
Start with finding the square root of n and check if it is a perfect square.
If not, then try to find the minimum number of squares required for the remaining number.
Repeat the process until the remaining number becomes 0.
Return the minimum number of squares required for the given number n.
- Q7. Insertion sort for a singly linked list.
- Ans.
Insertion sort for a singly linked list.
Traverse the list and compare each node with the previous nodes
If the current node is smaller, swap it with the previous node
Repeat until the end of the list is reached
Time complexity is O(n^2)
Interview Preparation Tips
Experience: There were 2 coding questions (no penalty for wrong submission) and 20 Multiple Choice Questions(with negative marking). We were given 90 minutes to solve them. MCQs were based on Data Structures, OS, CN, C outputs, OOP etc.
Tips: Experience in Competitive Programming might help in solving coding questions. No constraints were mentioned and detailed Instructions related to problem were stated vaguely. So code carefully.
Duration: 1 hour 30 minutes
Total Questions: 22
Round: Technical Interview
Experience: The interviewer asked me to introduce myself and a brief introduction of the projects that I have done. She first asked me questions related to my project. After that she moved on to the data structures part.
Tips: Take your time to approach the problems and if the question is not clear ask the interviewer to explain it again.
Round: Technical Interview
Experience: The interviewer asked me about how my previous round went. After that, he asked me to introduce myself and a brief introduction of the projects that I have done. He first asked me a few questions related to my project. Then he moved on to the data structures part. In this round the interviewer gave me strict time limit for coding the solution on paper for each problem and as soon as I was done coding he gave me 2-3 minutes every time to find errors and debug my code.
Tips: Do not panic even if the interviewer sets time limit while solving problems. If the question is not clear ask the interviewer to explain it again.
