Journey
Looking back, my journey to securing a role at EY GDS has been one of continuous learning, perseverance, and growth.
I started with the basics, gradually building my technical skills in programming, databases, and system design, while also working on problem-solving through consistent practice. Along the way, I explored different technologies, worked on real-world projects, and refined my understanding of core concepts.
One of the biggest lessons I learned was that consistency and hands-on experience matter the most. Beyond just theoretical knowledge, working on practical projects, coding challenges, and collaborating with peers helped me develop the confidence to tackle complex problems.
Equally important was honing my communication and interpersonal skills, which played a crucial role in my overall journey. Learning to articulate thoughts clearly, participate in discussions, and think critically helped me stand out during the selection process.
There were moments of self-doubt, but staying focused, adapting to challenges, and believing in my abilities kept me moving forward. I am grateful for the support of my mentors, peers, and the experiences that shaped my path.
Securing this role at EY GDS is a milestone, but I see it as just the beginning of an exciting journey ahead. To those aspiring to achieve their goals—stay persistent, embrace challenges, and keep learning. Success follows those who are willing to grow.
Application story
I applied for the Consulting Engineer role at EY GDS through my college's campus placement process. The application process was smooth, and all communication regarding the assessments and interviews was shared via official channels.
After submitting my application, I was shortlisted for the online assessment, which tested both aptitude and coding skills. Upon clearing it, I progressed to the communication assessment, evaluating my reading, speaking, and listening abilities.
Following that, I was invited for the technical interview, where my knowledge of core subjects was assessed. Lastly, I participated in the HR round, which primarily focused on communication and group discussion skills.
The entire process was well-structured, and regular updates were provided at each stage. It was a great learning experience, and I’m excited to start my journey with EY GDS!
Why selected/rejected for the role?
I believe I was selected for this role because of my strong grasp of fundamental concepts like OOPS, DBMS, OS, and SQL, along with my problem-solving skills and hands-on experience with projects. Additionally, my effective communication skills and ability to articulate my thoughts clearly during the interviews and group discussions played a crucial role.
This experience reinforced the importance of consistent learning, practical application, and confidence in tackling challenges. For aspiring candidates, I would emphasize focusing on both technical and soft skills, as both are equally important in securing such opportunities.

The first round was an online assessment designed to evaluate both analytical and coding skills. It consisted of:
Aptitude Section: Included 60 MCQs on quantitative aptitude, logical reasoning, and verbal ability to test problem-solving and critical thinking skills.
Coding Section: Featured a coding problems, which required logical implementation and knowledge of data structures and algorithms to solve efficiently.
This round was crucial in shortlisting candidates with strong logical reasoning, mathematical ability, and programming proficiency for the next stage.

Asked in companies
Given an array arr[]. Rotate the array to the left (counter-clockwise direction) by k steps.
Problem approach
Step 1: Initial Approach – Using a Temporary Array (Not In-Place)
I first considered a brute force approach using an extra array.
I copied the first d elements into a temporary array, then shifted the remaining elements left, and finally placed the stored elements at the end.
However, this required O(n) extra space, which was not optimal.
Step 2: Optimizing the Approach – Reversal Algorithm (In-Place)
The interviewer asked me to solve it in-place without extra space.
I then used the Reversal Algorithm, which works in O(n) time and O(1) space.
Final Optimized Solution: Reversal Algorithm
1. Reverse the first d elements → This moves the first d elements to the right in reversed order.
2. Reverse the remaining (n-d) elements → This moves the rest of the array to the left in reversed order.
3. Reverse the entire array → This places the elements in their correct rotated positions.

2. Listening Comprehension:
A short audio clip was played, and I had to answer questions based on what was said.
It tested attention to detail, key points, and ability to recall information accurately.
3. Speaking Section:
I was given a topic and had to speak fluently for a short duration.
The focus was on clarity, pronunciation, grammar, and coherence.
4. Sentence Correction & Grammar:

Asked in companies
Given an integer array, find three numbers whose product is maximum and return the maximum product.
Problem approach
Step 1: Understand the Key Observations
The maximum product of three numbers in an array can be achieved in two ways:
A. The product of the three largest numbers.
B. The product of the two smallest (most negative) numbers and the largest number (because multiplying two negative numbers results in a positive).
Step 2: Identify the Required Elements
To efficiently find the solution, we need:
A. The three largest numbers in the array → max1, max2, max3
B. The two smallest numbers in the array (most negative numbers) → min1, min2
Step 3: Choose an Efficient Approach
We have two main ways to find the required numbers:
Approach: Sorting (O(n log n))
Sort the array.
The answer will be:
max_product = max(nums[-1] * nums[-2] * nums[-3], nums[0] * nums[1] * nums[-1])
This works because:
A. nums[-1] * nums[-2] * nums[-3] gives the product of the three largest numbers.
B. nums[0] * nums[1] * nums[-1] gives the product of the two smallest and the largest number.
5. OOPS
Problem approach
Tip: Learn the basic concepts of OOPS.
6. Resume-based Questions
- Tell me about your projects.
- What frameworks did you use?
- What did you learn in your internship?
Problem approach
Tip: Go through your Resume properly and identify all the questions that you might get asked.
