Quick Stats

Applied through Pepper's careers portal in April 2026. A recruiter reached out within a few days. The process took about 3 weeks — standard for a fintech company at this stage. Being hybrid, they wanted to meet in person for the final rounds.

Round 1: Online Assessment

Format: 75-minute coding test Duration: 75 minutes What they were testing: DSA fundamentals, problem-solving, coding speed Interviewer approach: Automated

The assessment had 3 coding problems. One was a variation of the sliding window problem. Another involved implementing a basic transaction processor. The third was about detecting fraud patterns in transaction data — fitting for a fintech company.

I think I spent too much time on the fraud detection problem — it had more edge cases than I expected. Still, I cleared this round, so they probably look at overall performance rather than perfect solutions.

Round 2: Technical Round

Format: 60-minute video call with shared coding Interviewer: Senior Software Engineer Duration: 55 minutes What they were testing: Backend engineering, database design, fintech domain awareness Interviewer approach: Practical — focused on real fintech problems

The interviewer started with a warm-up: "Tell me about a challenging payment system you've worked on." I talked about implementing UPI integration at my previous company and handling edge cases like transaction failures and refunds.

Then we moved to coding. The problem was: design a simple ledger system that tracks account balances and transactions. I had to implement basic CRUD operations and ensure consistency.

His exact words were something like, "What happens if two transactions try to debit the same account at the same time?" That's when I brought up database transactions, row-level locking, and optimistic concurrency control. He seemed satisfied with the approach.

Round 3: System Design + Managerial

Format: 90-minute combined round (in-person) Interviewer: Tech Lead + Engineering Manager Duration: 85 minutes What they were testing: System architecture, fintech domain knowledge, culture fit Interviewer approach: Two interviewers — one technical, one behavioral

The system design problem was: design a payment gateway that can handle 100K transactions per second with sub-second latency. I started by clarifying requirements — what payment methods? What's the fraud detection requirement? How do we handle settlements?

I proposed a microservices architecture with separate services for authorization, processing, and settlement. The tech lead grilled me on data consistency — what if a payment is authorized but processing fails? How do we handle reconciliation?

I suggested a saga pattern for distributed transactions and an eventual consistency model for settlements. He pushed me on the implementation details — how do you handle idempotency? What about replay attacks?

Then the manager jumped in with behavioral questions. He asked about my experience working in hybrid environments, how I handle ambiguity in requirements, and my experience with regulatory compliance in fintech.

The Insider Section

Here's something most guides don't mention: Pepper (and fintech companies in general) puts a lot of emphasis on regulatory compliance. In my system design round, they asked about RBI guidelines, PCI-DSS compliance, and data localization requirements. If you haven't worked in fintech before, this can be challenging.

Also, they're big on testing. The interviewer asked about unit testing, integration testing, and how I'd test payment flows end-to-end. In fintech, a single bug can result in financial loss, so they're very serious about testing.

Compensation

The offer was ₹30 LPA base with a ₹4 LPA performance bonus and ESOPs. For an SDE-2 role in Mumbai in 2026, this is competitive with other fintech companies. The ESOP component was attractive — they're growing quickly and the upside potential is significant.

Honest Assessment

Who this role IS right for:

• Engineers interested in fintech and payments

• Those who want to work on high-scale financial systems

Who this role ISN'T right for:

• Someone looking for rapid experimentation and fast product iteration
• Engineers who prefer working on consumer-facing products over infrastructure
• People who don't care about the financial domain
