The Freshworks SDE Interview Guide
Freshworks, one of India’s most successful global SaaS companies (headquartered in Chennai/San Mateo), is known for its strong engineering culture and emphasis on building intuitive, scalable enterprise software.
The Interview Stages
The Freshworks interview process for Software Development Engineers (SDE-1/SDE-2) is rigorous but highly structured.
- Online Assessment: Algorithms and Data Structures on HackerRank/Codility.
- Technical Round 1 (Coding): Focus on problem-solving and algorithms.
- Technical Round 2 (Low-Level Design/Advanced Coding): Object-oriented design and advanced algorithms.
- Technical Round 3 (System Design - SDE 2+): High-level architecture.
- Managerial/HR Round: Cultural fit.
Round 1 & 2: Data Structures & Algorithms
Freshworks expects a very solid foundation in DSA.
- Topics: Expect medium to hard questions on Trees, Graphs, Hash Maps, and Dynamic Programming.
- Example: “Write a program to find the longest substring without repeating characters.”
- Evaluation: They look for optimal time and space complexity. You must write production-ready, clean code with proper variable naming.
Round 3: Low-Level Design (LLD) & OOPs
This is a critical round for Freshworks, as they build complex SaaS products.
- Question: “Design a simplified version of Jira (Issue Tracker) or a Ticketing System.”
- Focus: Define the classes (Ticket, User, Project), their attributes, and the relationships (1-to-many, many-to-many). Apply SOLID principles.
Round 4: System Design (For Laterals)
If you are applying for SDE-2 or above, you will have a high-level design round.
- Question: “Design a real-time chat application (like Freshchat) that handles 100,000 concurrent users.”
- Focus: WebSockets vs. Long Polling, database sharding, caching strategies (Redis), and handling message delivery guarantees.
Round 5: Behavioral (The “Kudumba” Culture)
Freshworks has a strong internal culture often referred to as a family (Kudumba in Tamil).
- They value humble, collaborative engineers who don’t have large egos.
- “Tell me about a time you helped a struggling teammate.”
- “Describe a situation where you had to learn a completely new tech stack in a very short time.”
Final Tip: Freshworks loves candidates who understand the SaaS business model. Mentioning concepts like multi-tenancy architecture during your technical rounds will significantly boost your profile.
