Interview preparation journey
Journey
It was a category two company, notified by our placement officer, exclusively for CSE students, with a salary range of 10-20 LPA. I was excited after reading its job description. We had a pre-placement talk session to learn more about this organization and the healthcare industry. Unfortunately, I was not selected for the second technical interview. Out of five students, only one received the FTE offer.
Application story
I was selected through the cutoff category for CSE students and applied to appear for the first online assessment (OA) round of interviews. I cleared the OA round and was selected to appear for the first technical interview round. However, due to a lack of understanding of system design concepts, I didn't make it to the second and final technical interview round. After not being selected, I focused on revising and improving my system design concepts.
Why selected/rejected for the role?
I was not selected for the final round of interviews due to my lack of understanding of system design concepts. After this experience, I focused on revising both low-level and high-level system design principles.
Preparation
Duration: 3 months
Topics: I revised all the data structures, algorithms, and OOPs concepts in C++. I also learned low-level system design concepts and solved some puzzles and quantitative questions for the interview.
Tip 1: Do revise the OOPs concepts of your primary language (mine is C++).
Tip 2: Revise all the DSA concepts to brush up on your problem-solving skills and review the system design concepts.
Tip 3: Practice some puzzles and quantitative problems, as they can help during interview rounds.
Application process
Where: Campus
Eligibility: 7.5 CGPA
Tip 1: Highlight only the tech stacks you are proficient in on your resume.
Tip 2: Mention projects you are confident in explaining, and specify the technologies you used to solve them.

At 6 PM, I was at the institute with all the selected CSE students, ready to appear for the OA round.
1. Password string
Easy
20m average time
80% success
0/40
Asked in companies
Given a password in a string, we have to determine whether the string satisfies all the conditions below: -
1 - Must contain a capital letter.
2 - Must contain a number.
3 - Must contain a special character.
4 - Must not contain the word “password” in any form.
5 - Length should be of more than 7 characters and less than 31 characters.
Problem approach
I traversed the string up to the point where all the above 4 conditions were met and for the 5th condition, I only compared the length to the given range.
2. Find the Missing Digit in an Equation
Easy
10m average time
90% success
0/40
Asked in companies
An equation is given in the form of a digit represented by x, need to find the value of x from the equation.
Example: 75 / x5 = 3, output will be 2 here.
Problem approach
First I designed a helper method to decide which mathematical operation needs to be performed based on the given equation.
Secondly, I keep traversing a loop from x=0 till I get the value of LHS equals RHS.
3. Merge sort problem.
Easy
15m average time
85% success
0/40
Asked in companies
Given a sequence of numbers ‘ARR’. Your task is to return a sorted sequence of ‘ARR’ in non-descending order with help of the merge sort algorithm.
Example :
Merge Sort Algorithm -
Merge sort is a Divide and Conquer based Algorithm. It divides the input array into two-parts, until the size of the input array is not ‘1’. In the return part, it will merge two sorted arrays a return a whole merged sorted array.
The above illustrates shows how merge sort works.
Note :
It is compulsory to use the ‘Merge Sort’ algorithm.
Problem approach
I applied the best-case complexity approach of merge sort to solve this problem.

Coding problem3
In the afternoon, I was at my institute to appear for the interview along with four others after the OA round.
1. OOP Concepts, Problem-Solving Strategies, and Sorting Algorithms
~ Asked me about the OOPs concept in C++, static and non-static methods.
~ Asked about how I had approached the online assessment round problems.
~ Asked about different sorting algorithms and merge sort specifically.
Problem approach
Tip 1: Revise the DSA and OOPs concept for such questions.
Tip 2: Keep in mind your steps while solving the OA round problems.
Tip 3: Revise the different sorting algorithms and ways to reach optimized solutions in solving them.
3. System Design
~ Asked me to explain about low-level design approach.
~ The interviewer asked me about the system design steps of my projects in my resume.
~ The interviewer gave me a problem statement and asked me to build the system design of the problem.
Problem approach
Tip 1: Revise the system design concept of any mock problem statement and know the basics of it.
Tip 2: Memorize the steps of designing solutions to the projects mentioned in your resume.
Tip 3: Don't hesitate to ask for help and discuss the approach to the problem statement.

It was in the afternoon at the institute. Unfortunately, I wasn't able to clear the first technical round, so I didn't appear in the final technical round. Only one student was selected for that round.
