Selected Interview preparation journey
Journey
I received an HR call, and they scheduled the first round. In this round, the interviewers asked about basic DSA concepts, and I needed to solve problems with better time complexity. The questions were at a medium level. After clearing this round, there will be two technical rounds and one managerial round.
Application story
I just applied through Naukri, and my resume was selected. Resume building is important; mention your projects, your tech stack, and all your technical strengths on your resume.
Why selected/rejected for the role?
I have a strong technical background. I applied for a mobile development role and have in-depth knowledge of advanced architectural frameworks like VIPER and MVVM. I also perform unit testing and have experience with NCLC testing frameworks.
Preparation
Duration: 3 months
Topics: For DSA, I mostly used coding platforms.
Tip 1: As I mentioned, do algorithm and DSA practice daily.
Tip 2: In your daily tasks, try to understand the basics of any language and concept.
Tip 3: Write as much code as you can. If you don’t get many opportunities in your daily job, try to create some projects on your own.
Application process
Where: Naukri
Eligibility: Minimum 5 years of experience
Tip 1: Mention all your projects with their links.
Tip 2: Mention the tech stack, testing framework, and any other relevant details needed for the role.

Asked in companies
You have been given an array/list 'ARR' of integers. Your task is to find the second largest element present in the 'ARR'.
Note:
a) Duplicate elements may be present.
b) If no such element is present return -1.
Example:
Input: Given a sequence of five numbers 2, 4, 5, 6, 8.
Output: 6
Explanation:
In the given sequence of numbers, number 8 is the largest element, followed by number 6 which is the second-largest element. Hence we return number 6 which is the second-largest element in the sequence.
Problem approach
I solved it in a single loop using 2 variables.
