Interview preparation journey
Application story
I received a referral for this role from my college senior, and the very next day I got a call from HR. She conducted a brief telephonic screening and scheduled my technical interview for the following day.
The interview lasted around one hour, during which the interviewer asked questions across multiple topics, covering all the key areas relevant to an Automation Engineer role.
Why selected/rejected for the role?
I was well-prepared in API Testing, API Automation, and UI Automation. However, I had not prepared sufficiently for Object-Oriented Programming (OOPs) concepts, and the interviewer asked in-depth questions in this area.
In Data Structures and Algorithms (DSA), I was given one medium-level and one hard-level problem. I was able to solve the medium-level question, but I couldn’t fully complete the hard-level one.
Additionally, I was asked to write an SQL query, which I had not prepared for.

Coding problem2
1. Reverse Each Word
Easy
0/40
Asked in company
Aadil has been provided with a sentence in the form of a string as a function parameter. The task is to implement a function so as to print the sentence such that each word in the sentence is reversed.
Example:
Input Sentence: "Hello, I am Aadil!"
The expected output will print, ",olleH I ma !lidaA".
Problem approach
I uses the idea of a stack, Here are the step by step Which I follow to solve this problem
1:- Traverse the string character by character (Read the input from left to right.)
2:- Store characters of a word temporarily
3:-Reverse the word using stack behaviour
4:- Maintain spaces(After reversing a word, add a space to separate words.)
5:- Handle the last word
2. Trapping Rain Water
Moderate
15m average time
80% success
0/80
Asked in companies
You have been given a long type array/list 'arr’ of size 'n’.
It represents an elevation map wherein 'arr[i]’ denotes the elevation of the 'ith' bar.
Print the total amount of rainwater that can be trapped in these elevations.
Note :
The width of each bar is the same and is equal to 1.
Example:
Input: ‘n’ = 6, ‘arr’ = [3, 0, 0, 2, 0, 4].
Output: 10
Explanation: Refer to the image for better comprehension:
Note :
You don't need to print anything. It has already been taken care of. Just implement the given function.
Problem approach
I was able to explain the brute force approach for the problem. In this approach, for each index, I calculate the maximum height to its left and the maximum height to its right. Then, the water stored at that index is determined by taking the minimum of these two values and subtracting the current height. However, I was not able to further optimize this approach.
