The Process

Applied through LinkedIn. Nasdaq is a global technology company providing trading and exchange technology, so they expect engineers who understand financial markets.

Round 1: Recruiter Screen (30 minutes)

The recruiter mentioned this was for their fintech team in Mumbai, building trading and market data platforms.

"Do you have experience with financial markets or trading systems?"

I was honest — I'd worked on a fintech project but didn't have deep trading systems experience. She said that was fine as long as I was willing to learn the domain.

Round 2: Coding Round (60 minutes)

Standard coding round on HackerRank with three questions: order book implementation, market data processing, and rate limiter design.

Round 3: Fintech Domain Round (60 minutes)

This is the unique round that sets Nasdaq apart.

"Explain how an order book works in electronic trading."

I explained the concept of buy and sell orders, price-time priority, order matching, and trade execution. I discussed different order types (market orders, limit orders, stop orders).

"Design a data structure for an order book that supports efficient order matching."

I proposed using two priority queues — one for buy orders (sorted by price descending, then time) and one for sell orders (sorted by price ascending, then time). I discussed the time complexity of insertions and matches.

"How do you handle high-frequency trading requirements?"

I discussed the need for ultra-low latency, using in-memory data structures, minimizing garbage collection, and using lock-free algorithms where possible.

"Explain market data feeds and how to process them in real-time."

I talked about different market data protocols (FIX, ITCH,OUCH), the challenges of processing high-volume data streams, and using message queues for buffering.

Round 4: System Design Round (60 minutes)

"Design a real-time market data distribution system that can handle 1 million updates per second."

I proposed an architecture with:

• Market data ingestion layer
• Normalization and enrichment service
• Distribution layer using multicast or publish-subscribe
• Caching layer for historical data
• Monitoring and alerting

"How do you ensure data consistency across multiple data centers?"

I discussed active-active replication with conflict resolution, using consensus protocols like Raft for leader election, and handling network partitions.

"How do you handle regulatory requirements like audit trails?"

I designed an immutable audit logging system that captures all market data updates and trades. We discussed regulatory requirements like MiFID II and the need for complete audit trails.

Round 5: Manager Round (45 minutes)

"Why Nasdaq specifically?"

I talked about their unique position at the intersection of technology and financial markets, and their work on next-generation trading platforms.

"Tell me about a time you had to learn a complex domain quickly."

I talked about learning healthcare data standards for a previous project, and how I applied a similar approach to learning fintech concepts.

The Insider Insight

Nasdaq invests heavily in training their engineers on financial markets. They have internal courses on trading mechanics, market microstructure, and regulatory compliance that all engineers go through. They don't expect you to be an expert upfront, but they do expect curiosity and willingness to learn the domain deeply.

Compensation

The offer was ₹36 LPA base with a performance bonus that brings total comp to about ₹43 LPA.

Who This Role Is Right For

This role is perfect if you're interested in financial technology, want to work on trading systems, and enjoy learning complex domains.

It might not be for you if you prefer generalist roles or find financial markets intimidating.
