Selected Interview preparation journey
Journey
Before transitioning to my Software Development Engineer (SDE) role, I worked as an Electrical Engineer for two years. My interest in software development led me to learn coding, and after approximately six months of dedicated learning, I applied to around 30 companies. I received interview opportunities from several organizations, including Tech Mahindra, Sharechat, Qubited, Cloud Bloom, and many more. Ultimately, I received job offers from Tech Mahindra and Qubited. I chose to join Qubited primarily because they offered a work-from-home facility, which aligned well with my preferences.
Application story
I comes to know about the SDE role vacancy from linkedin job section. I applies their and after a week I got a screening call and then Test link and after 3 days my interview is scheduled.
Why selected/rejected for the role?
As my role was for frontend development specifically, my interview was mostly focused on frontend development technologies and JS libraries like React JS and React Native, along with some basic-level DSA questions. As I mentioned, I was well-prepared for interviews because I had attended many before this, and compared to others, this one was relatively easy for me. Consequently, I got selected.
Preparation
Duration: 8 months
Topics: Sorting, Tree, Dynamic programming, Pointers, Greedy, React Js, React Native, Database, System Design
Tip 1: For DSA preparation, start with basic-level questions, then move on to medium-level questions, and finally attempt a few hard-level questions. If you are unable to solve hard-level questions, don't worry too much. The most important thing is to use the pen and paper method to solve the question before writing code in an IDE.
Tip 2: Create some awesome projects to showcase during interviews.
Tip 3: Focus on improving your communication skills and participate in mock tests with friends.
Application process
Where: Linkedin
Eligibility: No Criteria
Tip 1: Add at least 2 great projects on which you are confident. Ensure they are deployed on a server.
Tip 2: Try to keep your resume filled with genuine data, and ensure that you have every topic and information on your resume memorized. The resume should not exceed 1 page in size.

1. Move Zeroes To End

Asked in companies
Given an unsorted array of integers, you have to move the array elements in a way such that all the zeroes are transferred to the end, and all the non-zero elements are moved to the front. The non-zero elements must be ordered in their order of appearance.
For example, if the input array is: [0, 1, -2, 3, 4, 0, 5, -27, 9, 0], then the output array must be:
[1, -2, 3, 4, 5, -27, 9, 0, 0, 0].
Expected Complexity: Try doing it in O(n) time complexity and O(1) space complexity. Here, ‘n’ is the size of the array.
Problem approach
Step 1: I applied the brute force technique (I took another array and traversed the first array, separating all zeros. Then, I traversed again and moved the remaining elements).
Step 2: The interviewer asked me about the time complexity and space complexity of the solution.
Step 3: Then, they asked me not to use extra space.
Step 4: I came up with the two-pointers method, and he was satisfied with my solution.
2. Valid Parentheses

Asked in companies
You're given a string 'S' consisting of "{", "}", "(", ")", "[" and "]" .
Return true if the given string 'S' is balanced, else return false.
For example:
'S' = "{}()".
There is always an opening brace before a closing brace i.e. '{' before '}', '(' before ').
So the 'S' is Balanced.
3. Project Related Questions
Que 1: Explain the whole project, its tech stack, working process, and its main features. What was my role and responsibility in the project?
Que 2: Why did I choose this particular tech stack to create my project?
Que 3: What problems did I face during my project?
Problem approach
Tip 1: Be prepared for all types of questions about your project thoroughly, even if you have worked on the project in a team. You should have knowledge about every aspect and feature of the project.
Tip 2: Have your project ready before the interview and ensure that all its links are working fine.
