Journey
1. Everything starts with the fundamentals. You should practice and learn such that you are confident enough to tackle anything, whether it is CS fundamentals or any tech-stacks. 2. Then comes DSA. It is most essential for the OA-CODING ROUNDS. Set small targets and fulfill them with dedication. 3. In today's market, I have seen that the need for skillful persons has increased. You should be competitive enough with your skills, like DevOps, etc. Make really good projects to stand out from others.
Application story
The process comprised an Online Assessment (OA) and interview rounds. The OA had a total of 4 questions, equally divided into Medium and Hard sections. I solved 3 questions out of 4. For the offline interview round, there was a panel of 4 interviewers, and the whole round lasted around 15-20 minutes. This round was mainly about the skills and projects mentioned in the resume that I took with me.
Why selected/rejected for the role?
selected along with few more students, overall ,a really great experience. medium level interview I would say.

OlaPaytm (One97 Communications Limited)Amazon

You are given an array 'arr' of size 'n' having unique elements that has been sorted in ascending order and rotated between 1 and 'n' times which is unknown.


The rotation involves shifting every element to the right, with the last element moving to the first position. For example, if 'arr' = [1, 2, 3, 4] was rotated one time, it would become [4, 1, 2, 3].


Your task is to find the minimum number in this array.


Note :
All the elements in the array are distinct. 


Example :
Input: arr = [3,4,5,1,2]

Output: 1

Explanation: The original array was [1,2,3,4,5] and it was rotated 3 times.

You are given a Binary Tree.


Return the length of the diameter of the tree.


Note :
The diameter of a binary tree is the length of the longest path between any two end nodes in a tree.

The number of edges between two nodes represents the length of the path between them.
Example :
Input: Consider the given binary tree:

Example

Output: 6

Explanation:
Nodes in the diameter are highlighted. The length of the diameter, i.e., the path length, is 6.


Problem approach

Similar to the above question, but it was very tricky to understand. So, I would say, be careful while reading the question; don't just assume things. Think about the data structures that would implement with the given constraints. Try to run a few test cases in mind on your algorithm, then proceed with the approach.

1. Conceptual Questions

PostgreSQL vs Cassandra DB. (Learn)

NodeJS and its asynchronous nature. (Learn)

Disadvantages of ReactJS and better alternatives. (Learn)

 

Problem approach

Be confident in your answers, show your motivation, and most importantly, be clear about your fundamentals. It all comes down to fundamentals. Make really good projects because most of the time can be covered in explaining the projects. Also, be ready with a live demo. I showed my projects on my phone, and they were really impressed.
