Interview Preparation, Presentation & Common Viva Questions
What to say in the opening (introduce yourself) — recommended script and tips
“Good morning Sir/Madam. I am Dr. [Name]. I completed MBBS from [College, Year], and my internship at [Hospital]. I have completed/doing my post-graduation in [specialty] from [Institute]. Currently, I am working as [designation] at [hospital]. I belong to [city/state].”
Tips: Keep it short (20–30 seconds), mention key clinical experience and motivation for public service. The board wants clarity, confidence and a sense of public-service intent.
Common personal & behavioral questions — model answers
A: A personal, truthful line linking service orientation and scientific interest — e.g., “I was inspired by the ability of medicine to relieve suffering and help communities; my clinical work reinforced my interest in public health.”
Q: “What are your strengths and weaknesses?”
A: Strengths: team-player, calm in emergency, good communication. Weakness: occasional over-detailing — now improved by time-bound decision-making. Avoid cliché or irrelevant answers.

Interaction with Administration — IAS / District Leadership (Chairman) — (Top Section)
Why this matters: As a CHS officer you will work closely with the District Administration. Interviewers often test your understanding of administrative roles, crisis coordination and realistic execution of public-health programmes at the district level.
1. Who is the District Collector / DM / Chairman and what is their role in health emergencies?
- Convenes and chairs the district emergency response committee (control room, SitRep coordination).
- Allocates logistics (isolation centers, ambulances, transport, temporary infrastructure), unlocks funds and imposes administrative measures (movement restrictions, containment) if required.
- Coordinates cross-sectoral departments — Police (for enforcement), Revenue (for space), Education & ICDS (for outreach), Public Works (for infrastructure), and Municipal bodies for sanitation.
- Serves as the district-level link with state and national authorities, and signs off on orders and public advisories.
2. How should a CHS officer coordinate with the District Collector / IAS Chairman?
- Timely Situational Reports (SitReps): Provide concise data — number of cases, bed occupancy, oxygen availability, ICU usage, health workforce gaps, urgent logistics needed (e.g., PPE, oxygen cylinders).
- Actionable Requests: Don’t just say “we need help” — propose specific asks: 10 oxygen cylinders, one ambulance with driver, permission to requisition a community hall for isolation, temporary recruitment of paramedics for 7 days, security for vaccination team, etc.
- Use administrative channels: Follow the chain of command, submit written briefs when asked, request urgent orders for resource allocation or law enforcement when community measures are needed.
- Intersectoral approach: Request support from Revenue for shelter, Police for crowd control, Education for using school halls for temporary clinics, and Municipal bodies for sanitation and vector control.
- Data transparency: Keep accurate logs and daily reports; be ready to justify choices with numbers (patients per bed, bed turnover, referral times).
- Communication style: Keep presentations short, evidence-based (figures/tables), and offer two options with pros/cons (low cost/fast vs high cost/long-term). Use “Sir/Madam” and respect formal protocol in person, but be practical in the field.
3. If the DM asks you to set up a fever clinic in 24 hours, what steps will you take?
- Assess needs & site: Identify available space — PHC annex/community hall/school room. Ensure water, sanitation and power supply.
- Define staffing: 1 Medical Officer (MO) + 2 nurses + 2 ANMs/ASHA + support staff (data entry, cleaner). Arrange Roster for shifts to provide 12–24 hour coverage.
- Equipment & supplies: Tents/room dividers, beds/bedsheets, PPE kits, oxygen concentrators (if possible), pulse oximeters, thermometers, BP apparatus, glucometer, rapid antigen kits/NS1/IgM kits, basic medicines (paracetamol, antiemetics), emergency referral phone number/ambulance contact.
- Infection prevention & control (IPC): Arrange hand hygiene stations, waste segregation bins (BMW color-coded), signage for patient flow (screening → triage → treatment → referral), cleanable surfaces, staff training on donning/doffing.
- Referral pathway: Clear SOP for escalation to higher centre (who to call, what documents to send, transport plan) and contact list of nearest district hospitals with ICU/oxygen capacity.
- Admin approvals: Request DM for permissions, police/help for crowd control, and municipal help for sanitation. Get quick supply orders approved via emergency funds.
- Communication: Public IEC informing community about hours, location, and services; ask local health volunteers/ASHA to guide patients.
4. How to brief an IAS officer in the field or boardroom?
- One-line problem statement: e.g., “Sir, we have 27 new dengue admissions and oxygen supply is sufficient for 24 hours at current usage.”
- Evidence (2–3 metrics): Active cases, bed occupancy, oxygen cylinders remaining (number & location), staff availability, referral bus status.
- Two options: Option A (immediate, low-cost) and Option B (sustainable). Example: Option A — set 20-bed triage unit using school hall today (requires 2 drivers, 5 oxygen cylinders). Option B — transfer moderate cases to district hospital and set up oxygen plant (2–3 days, requires procurement). Mention pros/cons.
- Specific requests: e.g., approval to requisition school hall, release of ₹50,000 contingency funds, deployment of ambulance from nearby block.
- Conclude: “If approved, we will operationalize within X hours and send the first SitRep in 6 hours.”
5. Common interview questions related to IAS coordination (sample answers):
A: Plan: Pre-drive community meetings with Panchayat/Local leaders (facilitated by DM), ASHA mobilization, IEC (local language) addressing myths, arrange convenient timings, and ensure transport support for elderly. Provide daily feedback to DM and resolve logistic bottlenecks quickly.
Q: “If the DM insists on an administrative measure you disagree with medically, what do you do?”
A: Professionally present clinical evidence with clear risks/benefits, propose alternative approaches, offer to run small pilot to assess outcome, and if decision stands, implement with safeguards while documenting my concerns and rationale.
Medicine — Detailed Q&A
Define Pyrexia of Unknown Origin (PUO). Why the examiner asks this?
Approach: Stepwise:
- Reassess history & exam: Travel, zoonoses, occupational exposures, TB contact, weight loss, lymphadenopathy, night sweats, drug history (drug fever), and immunosuppression.
- Basic tests: CBC, ESR/CRP, peripheral smear, blood cultures ×3 (aerobic), urine culture, LFT, RFT, chest X-ray, abdominal ultrasound.
- Targeted tests: TB workup (sputum AFB/CBNAAT, Mantoux/IGRA), echocardiography (endocarditis suspicion), serology (brucella, leptospirosis, malaria smears or RDT), autoimmune markers (ANA, ANCA) if indicated.
- Advanced imaging/biopsy: Contrast CT chest/abdomen or PET-CT if available; biopsy of accessible lymph node or bone marrow if indicated.
- Management: Avoid empirical broad-spectrum antibiotics without clues; treat identified cause specifically. If no cause and patient stable, plan structured follow-up and reassess periodically.
Exam tip: Emphasize systematic approach: “History → Basic labs → Imaging → Targeted tests → Biopsy.” That shows methodical reasoning.
How is dengue fever managed? (Exam-focused answer)
Management:
- Supportive fluids: Oral rehydration for mild cases; IV crystalloids for warning signs or dehydration. Monitor Hct & hemodynamics regularly.
- Avoid: NSAIDs (risk of bleeding) and steroids (no proven benefit).
- Monitor: Hematocrit, platelets, vital signs, urine output.
- Transfusion: Platelet transfusion only for active bleeding or platelet count <10,000/mm³ (or per physician guidance if clinically bleeding at higher counts).
- Severe dengue: Treat for shock with careful fluid resuscitation, blood products if needed, ICU monitoring.
What are the first steps in suspected myocardial infarction (MI)?
- Morphine for severe pain (cautiously),
- Oxygen if SpO₂ < 90%,
- Nitrates sublingual (if not hypotensive),
- Aspirin 325 mg chewable immediately, clopidogrel loading as indicated.
Reperfusion: Primary PCI preferred if available within 90 min. If not feasible, give thrombolysis (tenecteplase/alteplase) within 12 hours for ST-elevation MI. Admit and monitor for complications (arrhythmias, heart failure).
Emphasize “time is muscle” and speak of secondary prevention (statin, ACE inhibitor, beta-blocker as indicated).
How would you manage an unconscious patient presenting to the ER? (ABCDE)
- Airway — check patency, remove obstruction, consider oropharyngeal airway or intubation if GCS ≤ 8.
- Breathing — oxygen, check respiratory rate, auscultate, provide ventilation if inadequate.
- Circulation — IV access, fluids if hypotensive, check pulse, ECG, control external bleeding; check blood sugar (treat hypoglycemia immediately).
- Disability — assess GCS, pupils, lateralizing signs, check for seizures; give IV dextrose if low sugar; treat seizures with IV benzodiazepines.
- Exposure — look for trauma signs, rashes, needle marks, observe environment; keep warm.
Antibiotic resistance — what is it and how can it be prevented?
Mechanisms (short): Genetic mutation, horizontal gene transfer (plasmids), enzyme production (e.g., beta-lactamases), efflux pumps.
Prevention:
- Rational prescribing — only when bacterial infection is likely; use narrow-spectrum agents when possible.
- Complete therapeutic courses; avoid self-medication and over-the-counter antibiotic use.
- Hospital infection control — hand hygiene, isolation, surveillance of resistant organisms.
- Antimicrobial stewardship programs — formulary control, de-escalation strategies, auditing prescribers.
- Public awareness and regulation of antibiotic sales.
Surgery — Detailed Q&A
How do you assess burns and calculate fluid requirement (Parkland formula)?
Classification of severity: Minor (<10% TBSA adult), Moderate (10–20%), Major (>20% TBSA) or any airway/face/circumferential/electrical burns.
Parkland formula: 4 mL × body weight (kg) × % TBSA (second and third degree only) = total crystalloid in first 24 h. Give half in first 8 hours from time of burn, remaining half over next 16 hours. Use Ringer Lactate. Monitor urine output (≥0.5 mL/kg/h).
What are first-aid measures for burns?
- Remove source of burn (stop chemical reaction, stop clothes on fire).
- Cool with running water for 10–20 minutes (avoid ice directly to prevent vasoconstriction/hypothermia).
- Remove constricting clothing/jewellery but do not remove tissue adhered to wound.
- Cover with clean dry cloth; analgesia; tetanus prophylaxis as needed.
- Do not apply ointments/ice/paste at scene.
Define strangulated hernia and provide management steps.
Presentation: Painful, irreducible swelling, signs of bowel obstruction (vomiting, distension), systemic toxicity if advanced.
Management: Immediate resuscitation (IV fluids, analgesia, antibiotics if suspected strangulation), NPO, NG tube if vomiting, urgent surgical exploration — reduce hernia or resect gangrenous bowel and perform appropriate hernioplasty/repair. Do not attempt forceful reduction in the presence of systemic signs.
Describe acute appendicitis management.
Investigations: CBC (leukocytosis), ultrasound (appendicular diameter >6 mm), CT if equivocal and resources available.
Management: Early appendectomy (laparoscopic preferred if available) with preoperative antibiotics; non-operative management with antibiotics may be considered in select situations, but exam answer should stress standard of care is appendectomy in most cases.
How do you manage trauma patient (ATLS primary survey)?
- Airway with C-spine protection (jaw thrust, chin lift; intubate if GCS ≤8).
- Breathing and ventilation (oxygen, chest tube for pneumothorax).
- Circulation with hemorrhage control (pressure, tourniquet if needed), 2 large-bore IV lines, crossmatch.
- Disability: quick neuro check (GCS), pupils.
- Exposure: undress patient, look for injuries, prevent hypothermia.
Paediatrics — Detailed Q&A
How to assess a newborn immediately after birth (Initial 30 seconds — Golden minute)?
- Dry and provide warmth (skin-to-skin or radiant warmer).
- Clear airway if needed (mouth then nose), position head slightly extended.
- Assess breathing and tone; stimulate if not crying.
- If breathing effectively and crying, routine care; if not — start positive pressure ventilation (bag & mask) within 60 seconds.
- Clamp cord after 30–60 seconds if baby stable; immediate clamping if resuscitation required.
What is the Apgar score and how is it used?
Causes and management of neonatal jaundice
Management: Use Bhutani nomogram to decide phototherapy/exchange transfusion. Phototherapy is first-line. Exchange transfusion in severe hyperbilirubinemia (values depend on age and gestational maturity) or neurological signs. Treat underlying cause (e.g., sepsis).
Management of pneumonia in a child (IMNCI approach)
Treatment:
- Non-severe pneumonia: Outpatient oral amoxicillin for 5 days, advice on feeding and danger signs.
- Severe pneumonia: Admit, IV Ampicillin + Gentamicin, oxygen therapy, monitor fluids and nutrition.
Obstetrics & Gynaecology — Detailed Q&A
What are the major causes of maternal mortality in India and measures to reduce MMR?
Indirect causes: Anaemia, heart disease, malaria.
Measures to reduce MMR: Strengthen institutional delivery (JSY), improve quality of intrapartum care (LaQshya), early referral systems, availability of blood and emergency obstetric care, routine antenatal screening and anemia control, MDSR (maternal death surveillance & response).
In interview, give specific schemes and a one-line systems approach: “Prevention through antenatal care, timely referral and quality emergency obstetric care.”
Define pre-eclampsia, eclampsia and HELLP syndrome. How are they managed?
- Gestational hypertension: New onset BP ≥140/90 after 20 weeks without proteinuria.
- Preeclampsia: Hypertension after 20 weeks with either proteinuria or end-organ dysfunction.
- Eclampsia: Preeclampsia with seizures (tonic-clonic) not due to other causes.
- HELLP: Hemolysis, Elevated Liver enzymes, Low Platelets — severe variant of preeclampsia, often third trimester.
Active Management of Third Stage of Labour (AMTSL) — steps and rationale
- Administer uterotonic (Oxytocin 10 IU IM) within 1 minute of delivery of baby.
- Delayed cord clamping (1–3 minutes) if baby stable.
- Deliver placenta using controlled cord traction (Brandt-Andrews technique) with counter-pressure if needed.
- Intervene for uterine atony if present (massage, repeat uterotonics, balloon tamponade or surgical steps if refractory).
What are the contraceptive options and indications for IUCD (CuT and LNG-IUS)?
IUCD: CuT — non-hormonal (copper) effective, can increase menstrual blood loss. LNG-IUS — reduces menstrual bleeding and is useful in heavy menstrual bleeding as well as contraception.
Contraindications: Pregnancy, active pelvic infection, unexplained vaginal bleeding, known uterine anomalies, certain cancers. Removal indicated for pregnancy, PID, severe bleeding, expulsion, uterine perforation, or patient desire for pregnancy.
For viva, highlight counselling points: informed consent, side effects, follow-up, and immediate postpartum insertion options.
Preventive & Social Medicine (PSM) — Detailed Q&A
Differentiate endemic, epidemic, pandemic, elimination and eradication (with examples)
- Endemic: Constant presence of disease in a geographic area (e.g., malaria in some NE states).
- Epidemic: Increase in cases above expected baseline in a defined area/time (dengue cluster/outbreak).
- Pandemic: Worldwide spread across countries and continents (COVID-19 declared a pandemic in 2020).
- Elimination: Zero incidence of disease in a defined area, continued surveillance needed (e.g., polio elimination in India 2014).
- Eradication: Permanent reduction to zero worldwide (smallpox eradicated 1980).
What is the Integrated Disease Surveillance Programme (IDSP) and steps of outbreak investigation?
Outbreak investigation steps:
- Confirm outbreak & verify diagnosis.
- Define & identify cases (case definition).
- Describe cases by time, place and person (epi-curve).
- Generate hypotheses on source and mode of transmission.
- Test hypotheses (analytical studies if necessary), do lab confirmation.
- Implement control and preventive measures (isolation, treatment, vector control, health education).
- Communicate findings and prepare a final report; continue surveillance.
Key national programs to remember (NTEP, NVBDCP, NPCDCS, AMB, Mission Indradhanush, Ayushman Bharat)
- NTEP (National TB Elimination Programme) — CBNAAT/TrueNat testing, Nikshay portal, free treatment, target: TB elimination by 2025.
- NVBDCP — vector borne disease control (malaria, dengue, kala-azar, filariasis, JE).
- NPCDCS — prevention & control of NCDs (screening adults ≥30 for HTN, diabetes, and cancers).
- Anemia Mukt Bharat (AMB) — 6×6×6 strategy (6 targets, 6 interventions, 6 institutional mechanisms) for multi-age group anemia reduction.
- Mission Indradhanush — drive to reach >90% full immunization coverage in children.
- Ayushman Bharat — Health & Wellness Centres (comprehensive primary care) and PM-JAY (insurance for secondary/tertiary care).
Biomedical waste (BMW) Management Rules — color coding & brief disposal steps
- Yellow: Yields — anatomical waste, soiled items, human/animal remains; incineration or deep burial where allowed.
- Red: Recyclable contaminated plastics — syringes without needles (where allowed), tubing, catheters (autoclave/shredder as per rule).
- White (Translucent): Puncture-proof sharps container for needles, scalpels, blades (autoclave/disable & then send for incineration as per local rules).
- Blue: Glass & metallic (vials, ampoules) — after disinfection send for recycling.
