System design for freshers

Most service-based fresher rounds do not ask system design. Some product-based or higher-band fresher rounds may ask short design basics or one system (for example: design a URL shortener). If you have 2–3 days, study scalability basics, one tiny design and a rate limiter — and skip deep internals like consensus or sharding algorithms.

system design puchte hai kya freshers se service based companies me

Service-based campus rounds (TCS NQT Ninja-level roles, Wipro Elite, Capgemini, Accenture mass tracks, Cognizant GenC) focus on aptitude, basic coding and communication. Their published test patterns do not list a system design section, and interview experiences students report rarely include it for freshers.

Where it may appear (based on 2024–2026 fresher interview reports): product-based fresher tracks or a higher band after a strong coding score (for example Digital/Prime-style bands), and intern-to-full-time conversions where the team tests design thinking. Even there, it is usually one system and a few scalability basics, not a senior design round.

system design puchenge kya freshers se Accenture ya Deloitte me

Accenture’s campus portal (checked 20 October 2026) describes behavioural, cognitive and communication steps and a coding assessment, but not a system design round for mass fresher hiring. Deloitte does not publish a fresher round list we could check (25 October 2026); students report an online assessment (aptitude and technical, sometimes coding), a spoken-English test, then technical and HR interviews, and their reports rarely mention system design for freshers.

If your role is product engineering, SDE or a higher band, a short design follow-up after coding (for example “How would you scale this?”) is possible. Prepare the 3-day plan below so you are not caught without a structure.

What to study in 3 days (and what to skip)

• Day 1: scalability basics. Latency vs throughput, horizontal vs vertical scaling, stateless services, load balancer, cache (Redis), database choice (SQL vs NoSQL), a content delivery network, a queue (Kafka), replication and the trade-offs between consistency, availability and network failures. No code — just when you would pick each.
• Day 2: one tiny design end to end. URL shortener: requirements (shorten, redirect, expiry, analytics), scale guess (clicks per second, storage), API (POST /shorten, GET /{code}), data model (code → URL, clicks), flow: Client → Load balancer → Service → Cache → Database, and the hard parts (code generation, hot keys, cache on redirect).
• Day 3: rate limiter. Fixed window vs sliding window vs token bucket; where it lives (gateway vs service); one text diagram. Practise saying it in 3 minutes.
• Skip for now: Paxos/Raft, deep sharding, consensus internals and “design Facebook from scratch”. For a fresher, showing a clean trade-off (“we cache redirects for speed but read through on miss for freshness”) scores more than reciting internals.

How to answer in the interview (60 seconds)

• Open (60-second script): “We need to shorten a URL and redirect quickly at scale. For, say, about 1,000 requests per second, I’d put a service behind a load balancer, cache hot redirects in Redis, store mappings in Postgres, and generate codes with a counter plus base-62.”
• Requirements: two or three things the system must do and one estimate of its scale (for example, “about 1,000 clicks per second”).
• High-level flow: one text diagram with 4–5 boxes; name each choice and its trade-off.
• Say the trade-off: “If we need fresher analytics, we delay aggregation; if we need faster redirects, we cache.”

Practise with Savyly

• System Design mode: Savyly gives requirements, rough estimates of traffic and storage, API and data model, a text diagram, the hard parts and trade-offs — then a short summary to say out loud. How practice interviews work.
• Mock design interviews: type /practice and pick system design — Savyly asks one system at a time and pushes on scale, APIs and trade-offs.
• DSA & Coding mode: for the coding rounds that come first, any problem on your screen → one key → idea, commented code and complexity. AI coding assistant.
