Cisco Software Engineer Interview Experience (2026) — Bengaluru

I got the offer. Here's exactly what happened at Cisco for the Software Engineer role.

• Role: Software Engineer
• Location: Bengaluru, Karnataka
• Year: 2026
• Timeline: 3 weeks, application to offer
• Rounds: Online Assessment → Technical Round 1 (DSA + Networking) → Technical Round 2 (System Design + Cloud) → Managerial Round
• Difficulty: Medium — strong focus on networking fundamentals and cloud concepts
• Outcome: Offer accepted
• Compensation: ₹12-20 LPA (depending on experience level)

Background

I was a fresher from a Tier-1 college with strong fundamentals in data structures and networking when I applied to Cisco. Their reputation in networking technology and the opportunity to work on cloud and AI-powered solutions appealed to me. I had prepared for 3 months focusing on DSA, networking basics, and cloud fundamentals.

Round 1: Online Assessment (90 minutes)

Format: Online coding assessment Duration: 85 minutes What they were testing: Problem-solving, coding speed, and basic networking knowledge

The assessment had 3 coding questions (easy-medium) and 10 networking MCQs. The coding questions were standard DSA problems - array manipulation, string processing, and a tree traversal problem. I managed to solve all 3 with optimal time complexity.

The networking MCQs covered:

• OSI model layers and protocols
• TCP vs UDP differences
• Subnetting and IP addressing
• Basic routing concepts

I scored well on both sections, which helped me clear this round.

Round 2: Technical Round 1 (60 minutes)

Format: Video call with shared coding Interviewer: Senior Software Engineer Duration: 55 minutes What they were testing: DSA, networking fundamentals, and problem-solving approach Interviewer approach: Started with coding, moved to networking discussion

This round began with a coding question:

"Implement a LRU Cache."

I implemented it using a HashMap and doubly linked list. He asked about time complexity — I explained O(1) for both get and put operations. He then asked about handling concurrent access — I mentioned using locks or concurrent data structures.

Then he moved to networking:

"Explain what happens when you type google.com in a browser."

I gave a comprehensive answer covering DNS resolution, TCP handshake, HTTP request, routing, and response handling. He asked about DNS caching — I explained browser cache, OS cache, and DNS server cache with TTL.

"What is the difference between TCP and UDP?"

I explained that TCP is connection-oriented, reliable, and ordered, while UDP is connectionless, unreliable, and faster. He asked when to use each — I gave examples: TCP for web browsing, file transfer; UDP for video streaming, gaming.

Round 3: Technical Round 2 (75 minutes)

Format: Video call with system design Interviewer: Staff Engineer Duration: 70 minutes What they were testing: System design, cloud knowledge, and scalability understanding Interviewer approach: Architectural discussion with trade-off analysis

He gave me a design problem:

"Design a URL shortening service like bit.ly."

I broke down my approach:

Requirements:

• Generate short unique URLs
• Redirect to original URLs
• Handle high traffic
• Analytics support

Components:

• Load balancer
• API servers
• Database (SQL for metadata, NoSQL for analytics)
• Cache layer (Redis)
• CDN for static content

Design Decisions:

• Use base62 encoding for short URLs
• Distributed ID generation (Snowflake)
• Database sharding for scalability
• Redis caching for frequently accessed URLs
• Async processing for analytics

He asked about handling hash collisions — I explained using unique IDs and checking database before assignment. He also asked about consistency — I mentioned write-through cache and eventual consistency for analytics.

Then he asked about cloud concepts:

"How would you deploy this on AWS?"

I suggested using:

• EC2 for application servers
• RDS for SQL database
• DynamoDB for analytics
• ElastiCache for Redis
• CloudFront for CDN
• Route 53 for DNS

He asked about auto-scaling — I explained using AWS Auto Scaling Groups based on CPU/memory metrics.

Round 4: Managerial Round (45 minutes)

Format: Video call with hiring manager Interviewer: Engineering Manager Duration: 42 minutes What they were testing: Team fit, communication, and career alignment Interviewer approach: Conversational with behavioral questions

We discussed my interest in networking and cloud technologies, my college projects, and why I chose Cisco. He asked about a challenging project I worked on — I shared an example of building a network monitoring tool where I had to handle packet capture and analysis.

He also explained Cisco's engineering culture: they emphasize innovation in networking and cloud, and encourage engineers to work on cross-functional teams. He asked about my long-term goals — I mentioned wanting to specialize in cloud networking and AI-powered solutions.

The Insider Section

Here's what most guides miss: Cisco places significant weight on your understanding of networking fundamentals, not just coding skills. In multiple rounds, they asked about OSI model details, protocol behavior, and network security concepts. They want software engineers who understand the infrastructure their code runs on.

Also, Cisco has been heavily investing in AI and ML. In my technical rounds, they asked about my exposure to ML frameworks and how I would apply AI to networking problems. They're looking for engineers who can work on AI-powered network solutions, not just traditional networking software.

Compensation

The offer came a week after the final round:

• For 0-2 years experience (freshers): ₹12-15 LPA
• For 2-4 years experience: ₹15-20 LPA
• Components: Base salary + joining bonus + performance bonus
• Benefits: Health insurance, ESOPs, learning budget, and gym allowance

For Bengaluru as a fresher from a Tier-1 college, this is competitive. Cisco pays well for candidates with strong networking fundamentals.

Honest Assessment

Who this role IS right for:

• Freshers and early-career engineers (0-4 years)
• People interested in networking and cloud technologies
• Those wanting to work on AI-powered solutions
• Engineers who enjoy understanding system infrastructure

Who this role ISN'T right for:

• People with no interest in networking (it's core to Cisco)
• Those wanting purely frontend work (roles are backend-heavy)
• Anyone expecting very high compensation compared to FAANG
• People who dislike learning new protocols and technologies

Cisco's Software Engineer interview is balanced between coding and networking. If you're interested in the intersection of software and networking, this is an excellent opportunity to work on industry-leading technology.
