Interview Preparation Tips
Experience: All the above questions were asked in full throttle right after another for approx 1 hour. Interviewer were well informed and were getting inside the skin of the candidate as far as sound knowledge was concerned. As such core technical wasn't examined but management skills were thoroughly analysed as per your CV. Their aptitude test wasn't an easy but to crack and some questions were so good that interviewer asked the same across the table to find out the logic of the candidate. Half an hour interview went on some stress basis as questions were easy but tricky (p.s. you won't expect a pythogoras theorem proving or an area of a circle proving to pop up).
Next gear of interview shifted to business analytics where basics of business e.g. profit maximization , price marking , resource allocation according to location and seasons were interviewed. Many situation based case studies were asked so as to test your management skills.
Last few mins were for your preference and ease of working.
Tips: Be genuine and generous.
Be positive.
Tackle every question properly.
Don't get demoralised in between the interview if you can't solve a question.
Be confident with a smile.
Round: HR Interview
Experience: This was a Skype round. It went for 45 mins approx. Believe me it was the hardest part as puzzles were very complex. But the best part is they watch out for your generalised approach towards solving your puzzles. Rest business analytics part was bit complex this time.
Tips: Be prepared.
Be composed.
Don't lose hope.
Don't make puppy face or demoralised body structure.
Solve puzzles and explain your approach even if it doesn't gets solved.

The interviewer asked to put everything on the blackboard and write down the code of each and everything.
Question : Explain all the search algorithm you know with space and Time complexities.
Answer : Linear search : It is a sequential search algorithm where the entire array is traversed till the desired element is not found. Time complexity is O(N) and auxiliary space is O(1).
Binary search : In this algorithm, a sorted array is searched by repeatedly dividing the search interval in half.
Steps :
1. Initially the interval covers the whole array.
2. If the value to be searched is less than the item in the middle of the interval, narrow the interval to the lower half. Otherwise, narrow it to the upper half.
3. The process is repeated until the value is found or the interval is empty.
Time complexity is O(log n) and auxiliary space is O(1) in case of iterative implementation.

- Q1. All the leaf nodes of tree are doubly linked,print only the leaf nodes of a tree
- Ans.
Print only the leaf nodes of a doubly linked tree.
Traverse the tree and check if a node has no children and both left and right pointers are null.
If yes, then it is a leaf node and print it.
If no, then continue traversing the tree.
Use recursion to traverse the tree in a depth-first manner.
- Q2. LRU page Replacement Algorithm for large data
- Ans.
LRU page replacement algorithm is used to replace the least recently used page in memory with a new page.
LRU stands for Least Recently Used
It is a cache eviction algorithm
It is used to manage memory in operating systems
It works by keeping track of the pages that are used recently and the ones that are not
When a new page is to be loaded into memory, the algorithm checks which page has not been used for the longest time

Traverse n nodes and continue reversing m nodes
Repeat the above step till the end of the linked list
Handle edge cases like m or n being greater than the length of the linked list
- Q4. Inorder Traversal of a tree
- Ans.
Inorder traversal is a way of visiting all nodes in a binary tree by visiting the left subtree, then the root, and then the right subtree.
Start at the root node
Traverse the left subtree recursively
Visit the root node
Traverse the right subtree recursively
Repeat until all nodes have been visited
- Q5. Inorder Travesal of a tree without recursion(write the code)
- Ans.

Myntra had conducted a coding test on campus before the start of the placement season with 2 questions, one on stack and other on DP.
Tips : For the test, the DP question asked was pretty standard, on Longest Common Subsequence. The question on stacks, I don't remember what it was but it was also pretty straight forward. For the test, I would recommend to solve problem from GFG. If they do come to resume shortlisting, they are looking for people who have done good projects and internships.

The interview started off with questions on my general interest in Software Development. The first round had two coding questions, I was supposed to write the code on paper.
For the questions, they asked me to code the solution first. And then gave a specific input and asked me to demonstrate step by step in my code, how it would lead to the correct answer.
Tips: It's ok if you can't code a general solution, if you can write a code which works for the particular input they have given then also it's ok with them. But be thorough with Data structures.

I wasn't asked to write any code in this interview. They asked me some questions on Machine Learning, because of my projects in them. Then they asked me if I knew graph algorithms. Since I knew BFS and DFS, I told them. They asked the difference between the two. Then they asked me if I knew how to find the shortest distance between two points in a graph. I didn't know Dijkstra's properly but I knew it worked on the greedy approach so was able to tell that. Then they asked me how would I find the second shortest path. I tried to answer it with the same greedy approach, but couldn't arrive at the complete solution.
Tips: They ask a tough theoretical question. It's ok if you don't know the answer, they only look for your approach.
