Trishul Defence Academy 
Imagine sitting in an interview room at Rashtrapati Bhavan, and for two and a half hours straight, senior officers grill you on the one subject you know least about — not to fail you, but to see if you’ll go home and study it overnight anyway.
That’s Stage 4 of the selection process for Aide-de-Camp (ADC) to the President of India. And the officer who went through it, Major Rishabh Singh Sambyal, has a story that starts exactly where every NDA aspirant reading this is standing right now — he joined the National Defence Academy at age 16–17, went on to command 4 Para Special Forces, and years later, was picked to serve at the highest level of the Republic. His journey isn’t a distant military story. It’s a mindset map.

Stage 1–2: You Are Already Being Shortlisted, Long Before the Big Day
Before a single interview happens, Service Headquarters shortlists 20–30 eligible officers based on their ACRs (Annual Confidential Reports), course gradings, and physical standards — years of consistent performance, not a single lucky day.
This is the single biggest myth NDA aspirants believe: that everything comes down to exam day. It doesn’t. Your Class 11 board performance, your daily fitness routine, your English speaking habit — all of it is quietly building the “record” that gets you shortlisted for SSB recommendation and beyond. There is no shortcut stage.
What to Build Starting Today
- Treat every school test and mock exam as part of your permanent “record,” not a throwaway attempt.
- Log daily fitness (running, push-ups) the same way an officer’s physical standards are tracked over years.
- Start SSB-style habits now — daily newspaper reading, English conversation — long before you’re anywhere near the interview room.
Stage 3–4: The 14-Day Pressure Test — And the Power of Studying Your Weak Point Overnight
Final ADC candidates live inside Rashtrapati Bhavan for 14 days, undergoing daily multi-hour interviews. Evaluators don’t just ask general questions — they identify a candidate’s specific gap, say geopolitics or world history, and grill them on it continuously for 2.5 to 3 hours. The real test isn’t whether you know the answer. It’s whether you have the drive to go study it overnight and come back stronger.
This maps directly onto how you should treat your weakest NDA subject. If Trigonometry scares you, or English grammar keeps costing you marks in mocks, that’s not a sign to avoid it — it’s the exact chapter that decides whether you have the “overnight drive” the Army is actually testing for.
The Weakness-Targeting Method for Your Own Prep
- Identify your single weakest chapter or subject honestly — no avoiding it.
- Give it a dedicated block this week, not “whenever I get time.”
- Test yourself on it the next morning — did the overnight effort move the needle?
- Repeat this cycle weekly on a rotating weak point until nothing is left untested.
Stage 5: Background Vetting Isn’t Just for Officers — Build a Character That Can’t Be Compromised
Multi-level background checks review a candidate’s childhood schooling, family record, and financial history — all to confirm the officer can’t be bribed, manipulated, or blackmailed later. Integrity isn’t assessed in a single interview. It’s assessed as a pattern across an entire life.
For an aspirant, this is a reminder that SSB’s Officer-Like Qualities aren’t a costume you put on for five days at the interview center. Cooperation, sense of responsibility, and self-confidence are habits examiners can spot instantly if they’re rehearsed rather than real.
The Special Forces Mindset: Clarity, Not Aggression
Major Sambyal is direct about one common misconception: the military mindset isn’t aggressive bravado. It’s the ability to think clearly when everything around you is chaos.
During 90-day Special Forces probation, candidates carry 70–80 kg loads across long distances under extreme sleep deprivation, and are still tested on visual observation — spotting a hidden object in dense trees while exhausted. The 72-hour stress phase pushes this further: continuous exertion without food or water, carrying a 30 kg backpack and 20 kg log, ending in an underwater test to see if panic sets in under pressure.
You will never face this exact test. But you will face a 150-minute Math paper with a ticking clock, sectional cutoffs breathing down your neck, and a question you can’t solve staring back at you. The transferable skill is identical: stay clear when the pressure spikes, instead of freezing or panicking.
Building “Clarity Under Chaos” Before Exam Day
- Practice full-length mocks under real time pressure — not comfortable, untimed revision.
- When you hit a question you can’t solve in the exam hall, treat it like the SF mindset: don’t panic, don’t force it, move on and come back later.
- Simulate a bad start deliberately in one mock — start weak on purpose and practice recovering, so a real bad start never rattles you.
The Philosophy That Ties It All Together: “Never Be Practical, Be Delusional”
Major Sambyal credits much of his journey to one belief: practicality binds people to comfortable limits, while achieving extraordinary goals requires dreaming beyond your current resources. He describes overcoming NDA and Special Forces hardships by looking in the mirror and fighting for the 16-year-old boy who dreamed of the uniform.
If you’re 15 or 16 and just starting NDA preparation, “being practical” might sound like the safe advice — study a little, aim for an average rank, keep your options open. But the aspirants who actually get commissioned are the ones who let themselves be a little delusional about the target, and then built the daily discipline to actually chase it.
FAQs: Applying the ADC Selection Mindset to NDA Preparation
Q: I’m not physically strong. Does the Special Forces mindset even apply to me?
Yes — the mindset described here is about mental clarity under pressure, not physical strength. It applies directly to how you handle a tough exam question or a bad mock test score.
Q: How early should I start building an SSB-ready character, not just exam knowledge?
Immediately. Background vetting and OLQ assessment reward years of consistent habit, not last-minute preparation — the earlier you start, the more authentic it looks by the time you’re interviewed.
Q: What’s the one thing I should do this week from this whole story?
Pick your weakest subject and give it a dedicated, honest study block — then test yourself the next day. That’s the overnight-drive test in miniature.
Your Next Step Starts Today
The path from a 16-year-old NDA cadet to Special Forces to Aide-de-Camp of the President wasn’t built on one lucky day — it was built on years of quiet, consistent discipline. Your NDA journey works the same way.
