Selected Interview preparation journey
Journey
During my B.tech, our seniors informed us how important DSA is to crack placements. Therefore, I started practicing DSA from GeeksFromGeeks, Leetcode and code studio right from my consecutive year. I practice a lot of questions. Also, I focused on core subjects as well properly.
Application story
The HR contacted me through email. I was asked to appear for the coding test. I applied through the link provided and then the further rounds were carried out.
Why selected/rejected for the role?
I was selected because I was able to answer all coding questions properly. I started with a naive approach and went ahead to explain the optimised approach for almost all the questions. Moreover, I had a deep understanding of OS concepts as well.
Preparation
Duration: 3 months
Topics: Data structures, Algorithms, System Design, Javascript, Database, OOPs
Tip 1 : Always keep your focus on learning the basics, they should be rock solid
Tip 2 : Don't try to cram things days or weeks before interviews, that never helps. Try to learn little by little every day incrementally.
Tip 3 : Don't try to target any specific company, it almost never works out, just stay true to yourself and keep doing the hard work, opportunity will come to you eventually.
Tip 4 : If you need to prepare in a short time, I would suggest doing the 30-day interview challenge on Leetcode
Application process
