It was a technical interview round where I was asked questions from my resume and questions based on DSA, OS, and DBMS.
The first interviewer asked me the following questions:
1. Detect the loop in the linked list and find the starting point of the loop.
2. The question was like this: Given an array of strings, find the first unique string in the array. For example, the given array is {“apple”, “mango”, “pear”, “apple”, “orange”, “pear”}. Here, both “mango” and “orange” are occurring once, but the answer is “mango” since it occurs before “orange” in the array.
Then the second interviewer started asking the following questions:
1. He gave me the inorder and preorder traversals of a binary tree and asked me to find its postorder traversal. He was only interested in the final answer.
2. What is a stack? What are some practical applications of stack? What operations can we perform on stack?
3. Name the sorting algorithms based on Divide and Conquer.
4. What is Selection Sort? What is its time complexity?
5. What are the differences between Array and Linked List? When will you use each of them?
6. What is a Minimum Spanning Tree? What are the algorithms to find MST?
7. Since my projects were based on Web Development, he asked different HTTP methods and what is the difference between authentication and authorization?
8. Write a SQL query to display the top 5 people with the maximum salary from an Employee table.
9. How is memory allocated in C and C++?
10. What is deadlock?
11. What are the differences between Process and Thread?
12. What are the differences between RAM and ROM?
13. A puzzle
At last, the interviewer asked if I had any questions for him.
You are provided with a singly linked list that may contain a cycle. Your task is to return the node where the cycle begins, if such a cycle exist...
To detect the first node of a cycle in a singly linked list, we can use the Floyd's Tortoise and Hare algorithm.
Use two pointers, slow and fast, to traverse the linked list.
If there is a cycle, the fast pointer will eventually catch up to the slow pointer.
Move the fast pointer twice as fast as the slow pointer.
Once the pointers meet, reset the slow pointer to the head of the linked list.
Move both pointers at the same s...

Tip 1 : For DSA questions in interviews, start explaining from the brute force approach and then move to the optimal one. Convey your thought process to the interviewers, so that they can help you out if you get stuck. Communication skills matter a lot, and I think that is what makes the difference!
Tip 2 : Do some research about the company you are interviewing for and prepare the answers to the questions like Why should we hire you? (frame your answer in such a way that shows that your career goals align with the goals of the company), Why XYZ company?, Competitors of XYZ, etc. beforehand. Read about some latest news related to the company so that you can ask questions based upon that when the interviewer allows you to ask any question. This shows that you are genuinely interested to work for the company.
Tip 3 : Spend proper time making your resume and get it reviewed by seniors. Do not write anything that you are not confident of. Even if you write something that you don’t know, just be prepared that how you will defend it. The interviewers are much much experienced than you and they’ll catch you easily if you lie. So don’t take risks here.
Tip 1 : Try to include at least 1 development project in your resume.
Tip 2 : Do not write anything that you are not confident of. Even if you write something that you don’t know, just be prepared that how you will defend it.

Move slow pointer by one node and fast pointer by two nodes in each iteration.
If there is a loop, both pointers will eventually meet at some point.
If there is no loop, fast pointer will reach the end of the linked list.
