Selected Interview preparation journey
Journey
I started preparing for my interviews during my third year of college. I practiced aptitude questions and referred to various websites and job interview questions. Additionally, I took a C++ coaching course, which sparked my interest in coding.
Application story
I applied through the company’s portal link provided by my college. After clearing the aptitude test, I proceeded to the technical round, followed by the final HR round, and ultimately received my offer letter.
Why selected/rejected for the role?
I was selected for the role. I remained confident throughout the interview, responding effectively to the interviewer’s questions. When I didn’t know the exact answer, I confidently shared related insights. I was thoroughly familiar with my resume and the projects I had worked on, presenting myself authentically.
Preparation
Duration: 3-5 months
Topics: DBMS, OS, OOP concepts, C++, data structures, web development
Tip 1: Implement OOP concepts in real-life scenarios.
Tip 2: Practice questions based on recursion, and don’t ignore basic or simple questions.
Tip 3: If you don’t have much time to prepare, focus on reinforcing your existing knowledge rather than trying to learn something new, as coding requires practice, not memorizing code or logic.
Application process
Where: Campus
Eligibility: 60% / First Class throughout 10th, 12th/Diploma, and Engineering; no active backlogs; 2-year gap allowed. (Salary Package : 3.25 LPA)
Tip 1: Don’t mention random projects that you aren’t familiar with or have copied from Google or elsewhere.
Tip 2: The interviewer may ask about anything on your resume, so be prepared for it.
Tip 3: Follow the current or updated resume format.
