I have 4 years of experience across two services companies, working primarily in banking. I applied for the Decision Analytics Associate Consultant role at ZS Associates' Pune office.
I reached out to the hiring manager directly via LinkedIn DM, and HR called me the next day to discuss my current role, the position, compensation, and day-to-day work scope. The entire process from outreach to first contact took just 2 days. HR also walked me through the interview structure and question themes upfront, which helped significantly with my prep.

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 the questions began. The case centered on TravelTreat, a digital platform competing against two rivals in the travel/hospitality space, with the following market data.

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.

The manager started with my resume — walking through why I chose analytics, my switch from banking to pharma, and deep dives into specific projects.
My approach was a multi-model layered targeting strategy: use data science to narrow the pool from 1M via feature engineering, demographics, age segmentation, and secondary research; run different models on the remaining cohort; bucket patients by similarity and target strategically. Then deploy personalized messaging and educate doctors and hospitals through sales reps.
The manager then pushed into operational details:
Guesstimates
JD-based questions
Puzzle
Where I got stuck: The rare disease case required real-time thinking about infrastructure costs, sales cadence, and model refresh cycles — I had to balance the sophistication of a multi-model approach against the economic constraints of a tiny patient population.

The second manager brought up a live project his team was working on, to gauge whether I could handle similar work on onboarding.
My initial answer was to match on latitude and longitude with a distance threshold. The manager pushed back — "What if there's a mountain between them?" — so I refined it: cluster hospitals by pincode first, then apply a distance threshold within each cluster to handle geographic edge cases.

I received and accepted the Decision Analytics Associate Consultant offer at ZS Associates, Pune — a ~30% hike with bimonthly Gurugram travel (accommodation covered) and performance-linked bonuses on top. Being in my final week of notice at my previous employer enabled fast scheduling between rounds.
Workload can be heavy with tight timelines, and there's a strong emphasis on client-facing exposure and direct stakeholder communication. Performance management is structured — underperformance can trigger a formal performance improvement plan.
