Gate-linked prep notes (2026)
For PSU-style hiring, candidates often combine GATE fundamentals with company aptitude/technical screens:
- Revise core branch subjects (not only coding)
- Practice numerical aptitude at campus-placement speed
- Revisit previous technical MCQs on this site
- Keep document readiness (gate scorecard if applicable, marksheets)
Extra technical drill
Q: Why do many PSU drives still test engineering fundamentals heavily?
Roles are often engineering-core, not pure software-product SDE. Expect thermodynamics / power systems / electronics / strength of materials style depth depending on your discipline, plus aptitude.
Q: Should CSE students ignore GATE topics for DRDO?
Not entirely. OS, DBMS, networks, and DSA still appear in technical rounds. Pair them with the aptitude mock on this site.
