How to prepare for infosys upcoming sp dse drives(2026 batch offcampus)?
​
Hi everyone,
I previously attempted the Infosys upgrade test but couldn’t solve any coding questions. I realize my DSA foundation is weak and I want to restart properly from basics.
I have a 1-month cooling period before I can apply again for Infosys SP/DSE offcampus, and I want to use this time effectively.
My goals:
Build strong DSA foundation for OA + interviews
Start Codeforces gradually
Become good enough for better off-campus opportunities
Background:
Basic Java knowledge
Not strong in DSA
Willing to study consistently for next few months
Questions:
How should I structure DSA prep for OA-level companies like Infosys SP/DSE?
How do I start Codeforces as a beginner without getting demotivated?
Any dsa sheet or pattern I can follow to start from beginning?
What else should I improve or learn apart from dsa to get shortlisted?
Any structured roadmap or personal experience would really help.
Thanks in advance 🙏
