Why I Failed Twice

Let me be honest — I was overconfident the first two times. I thought my MBA from a top college would be enough. It wasn't.

The first time, I got through the aptitude test easily but completely messed up the case study. The problem was about optimizing a loan approval process for a bank. I jumped straight into solutions without understanding the problem properly — rookie mistake. The interviewer actually stopped me midway and said, "You're solving the wrong problem."

The second time, I prepared better but still struggled with the financial modeling part. I could structure the problem, but my Excel skills weren't up to par. I took too long to build the model, and I made calculation errors. The interviewer was patient, but I could tell he wasn't impressed.

Third Attempt: The Aptitude Test

This time, I spent 3 weeks preparing specifically for eClerx. I practiced aptitude tests from previous years, focused on quantitative reasoning, and improved my Excel skills.

The aptitude test was 60 minutes with 50 questions:

• 20 quantitative (percentages, ratios, profit-loss, time-speed-distance)
• 15 logical reasoning (series completion, puzzles, data sufficiency)
• 15 verbal (reading comprehension, sentence correction, para jumbles)

I finished with 5 minutes to spare and double-checked my answers. The cutoff was high — they told me later it was around 35/50 — but I was confident I'd cleared it.

The Case Study Round: This Time I Was Ready

This was the make-or-break round for me. The case study was about a credit card company facing high customer churn. They gave me:

• Customer data (demographics, spending patterns, transaction history)
• Churn metrics (churn rate by segment, reasons for leaving)
• Competitor benchmarking data

I had 45 minutes to analyze and present recommendations.

Here's what I did differently this time:

1. Structured the problem first — I used the MECE framework (Mutually Exclusive, Collectively Exhaustive) to break down the churn problem
2. Asked clarifying questions — I spent the first 5 minutes understanding the business context instead of diving into data
3. Built a simple model — instead of overcomplicating the Excel sheet, I created a clean, interpretable model
4. Communicated my thought process — I explained my assumptions and the logic behind my analysis

The interviewer asked: "What would you prioritize if you only had budget for one initiative?"

I recommended focusing on the high-value customer segment because:

• They contributed 60% of revenue but had the highest churn rate
• The ROI on retention initiatives was highest for this segment
• Competitors were targeting them aggressively

He nodded and asked me to quantify the impact. I showed him my calculations — a 15% reduction in churn would save ₹2.4 crore annually. He seemed satisfied.

Technical Interview: Excel and SQL

This round was with a Senior Business Analyst and focused on technical skills. He asked me to solve a problem using Excel:

"Here's a dataset with 10,000 transactions. Find the top 5 products by revenue and calculate the month-over-month growth rate."

I used pivot tables, VLOOKUP, and conditional formatting to solve it. He asked about the formula I used for MoM growth — I explained the (current - previous) / previous formula and how to handle missing values. He also asked about advanced Excel functions like INDEX-MATCH and SUMIFS, which I demonstrated.

Then he moved to SQL:

"Write a query to find customers who made more than 5 transactions in the last month but haven't transacted in the current month."

I wrote a query with CTEs and window functions. He asked me to optimize it, so I added indexes and explained the query execution plan. He seemed impressed with my SQL knowledge — I think that's what set me apart from my previous attempts.

HR Round: The Final Hurdle

The HR round was straightforward but important. She asked about:

• Why I wanted to join eClerx specifically
• My understanding of the KPO industry
• My long-term career goals
• Salary expectations

For the "why eClerx" question, I talked about their domain expertise in financial services and their global client base. I mentioned that I wanted to work in a role where I could combine my analytical skills with industry knowledge.

The salary discussion was smooth. I asked about the growth trajectory, and she explained the promotion cycle and performance bonuses. We settled on ₹9 LPA base with a 15% performance bonus, which worked out to about ₹10.5 LPA total.

What Changed This Time

Preparation that worked:

• Practicing 20+ case studies before the interview
• Improving my Excel skills (pivot tables, advanced formulas, data visualization)
• Learning SQL properly — not just basic queries but joins, subqueries, and window functions
• Understanding the financial services domain (credit cards, loans, risk management)

Mindset shift:

• I stopped relying on my MBA pedigree and actually prepared
• I focused on communication and structuring over just getting the right answer
• I learned to be comfortable with uncertainty and ask questions when I didn't understand something
