I have 4 years of experience across two service companies — working primarily in banking. I applied for the Decision Analytics Associate Consultant role at ZS Associates' Pune office in March 2025.
I reached out to the hiring manager directly via LinkedIn DM. HR called me the next day to discuss my current role, the position they were recruiting for, compensation, and day-to-day work scope (client support and GTM strategy). The entire process from outreach to first contact took 2 days. HR also walked me through the interview structure and question themes upfront, which helped with prep.
Format: Virtual
Duration: ~45 minutes (scheduled for 30)
This was a DILR-style case study—Data Interpretation & Logical Reasoning in the style of a CAT exam. I was given time to read through the scenario before questions began.
The Case: TravelTreat
The case presented market data for TravelTreat, a digital platform competing against two rivals in the travel/hospitality space.
| Year | TravelTreat | Competitor A | Competitor B |
|---|---|---|---|
| 2015 | 96% | 75% | 87% |
| 2016 | 93% | 70% | 87% |
| 2017 | 92% | 76% | 89% |
| 2018 | 91% | 82% | 90% |
| 2019 | 95% | 85% | 88% |

Q1 — Competitive Position Assessment
I had to assess TravelTreat's competitive position relative to both hotels/resorts and end consumers (travelers) over 5 years, then explain the divergent trends between 2018–2019: TravelTreat maintained strong hotel partnerships but lost significant traveler share while Competitor A gained ground.
Q2 — Market Sizing Approach
I needed to outline an approach to estimate the market size (in $ ad revenue) for TravelTreat.com in 2021. I was asked what key pieces of information I'd need to collect.
Q3 — Digital Market Size Estimation
I was given actual 2020 U.S. market data and had to estimate the digital ad revenue market for 2021 with projected 10% growth across all segments.
| Segment | # of Hotels/Resorts | Avg Rooms per Property | % with Digital Ads | Annual Marketing Budget | Digital Ad Spend (Luxury only given) |
|---|---|---|---|---|---|
| Luxury | 2,000 | 300 | 80% | $50,000 | $30,000 |
| Midscale | 10,000 | 100 | 60% | $20,000 | Unknown |
| Budget | 50,000 | 30 | 40% | $10,000 | Unknown |
Additional context: 60% of hotel seekers use digital channels; 84% U.S. internet penetration; average occupancy 73%.
Q4 — Sales Force Sizing
I was given a table showing the relationship between annual calls/visits and sales output (in $'000s) for luxury/midscale vs. budget segments, along with rep costs and productivity metrics:
The Sales Ops Director wanted to retain 120 reps. I had to recommend the split between field and inside reps, then analyze viability and make strategic recommendations on sizing and composition.
Q5 — Puzzle: Three Doors, Two Guards
The classic logic puzzle: three doors (one freedom, two death), two guards (one truth-teller, one liar), you don't know which is which. I can ask only one question to one guard. What do I ask to guarantee I pick the freedom door?
Where I got stuck: The puzzle required a moment of reflection to construct a question that works regardless of which guard I'm asking. Once I framed it logically, it clicked.
Verdict: Cleared
Format: Virtual
Duration: ~1.5 hours (scheduled for 30 minutes, ran significantly over)
The manager started with my resume, asking me to walk through my career trajectory: why I chose analytics, my switch from banking to pharma, and deep dives into specific projects.
Main Case: Rare Disease Drug
A pharmaceutical company has a rare disease drug with a tiny addressable market—only 3 patients per 1 million population globally. The company has invested heavily and now needs to recoup ROI. How do we detect, reach, and market to these patients?
My approach:
The manager then pushed into operational details:
Guesstimates
JD-Based Questions
Puzzle: Sudoku-Style Grid
A 2×2 grid with images/numbers in three cells; identify the pattern and find what goes in the fourth cell.
Where I got stuck: The rare disease case required me to think through the operational logistics and cost structure in real-time. I had to balance the sophistication of a multi-model approach with the economic constraints of a tiny patient population.
Verdict: Cleared (HR called the next morning to schedule Round 3)
Format: Virtual
Duration: ~15 minutes (scheduled for 30 minutes, wrapped quickly)
The second manager brought up a live project his team was working on to gauge whether I could handle similar work on onboarding.
Q1 — Hospital Data Reconciliation
The challenge: there are two lists—one with hospital addresses, another with hospital names. The names don't match across lists (fuzzy matching has already been tried). How would I reconcile them?
My initial answer: match based on latitude and longitude with a distance threshold.
The manager pushed back: "What if there's a mountain between them?"
I refined my approach: cluster hospitals by pincode first, then apply a distance threshold within each pincode cluster to handle edge cases like geographic obstacles.
Q2 — Relocation Question
Why are you moving to Pune from Mumbai?
Verdict: Cleared (final call came 1 day later)
Format: Virtual
Duration: ~30 minutes
Scheduled: 3 days after Round 3
HR covered standard topics:
Offer Details
Work Culture Context
Workload can be heavy with tight timelines. The environment emphasizes client-facing exposure and direct stakeholder communication. Performance management is structured; underperformance can trigger a formal performance improvement plan.
Verdict: Cleared
I received and accepted an offer from ZS Associates for the Decision Analytics Associate Consultant role in Pune in March 2025. The process moved quickly—I was in my final week of notice at my previous employer, which enabled fast scheduling between rounds. The combination of case studies, manager interviews with both technical depth and business acumen testing, and HR alignment discussions gave ZS a comprehensive view of my analytical thinking, adaptability, and cultural fit.
