IIT Bombay campus interviews are highly competitive due to top companies like Google and Microsoft recruiting on campus, with coding rounds often featuring medium to hard problems. Expect a rigorous process including multiple technical rounds and behavioral assessments based on leadership principles. Dedicate 4-6 months to solve 300+ LeetCode problems and practice mock interviews with peers to match the difficulty.

Focus on core DSA topics frequently tested: arrays, strings, linked lists, hash maps, trees (binary, BST, traversals), graphs (BFS, DFS, shortest paths), dynamic programming, and heaps. Companies like Amazon and Flipkart often emphasize trees and graphs. Ensure you can implement data structures from scratch and optimize solutions for time and space complexity.

Common mistakes include not clarifying problem constraints, jumping into coding without an approach, poor communication of thought process, and neglecting edge cases. Always articulate your steps, write clean and modular code, and test with examples. In system design rounds, avoid skipping scalability and database considerations; use IIT Bombay's resources to practice structured responses.

Stand out by showcasing impactful projects or internships with measurable results, contributing to open-source, and participating in coding competitions like Codeforces. In behavioral rounds, use specific STAR-method examples from IIT Bombay coursework, hackathons, or club leadership to demonstrate problem-solving and teamwork. Leverage IIT Bombay's alumni network for referrals and insights.

Placements start with pre-placement offers in July-August for pre-final year students, with the main season from December to January for final year. Companies typically respond within 1-3 weeks post-interview, but delays can occur. Monitor the IIT Bombay Career and Placement Service (CPS) portal regularly and follow up politely if needed.

SDE-1 is for fresh graduates, focusing on coding tasks with mentorship. SDE-2 requires 2-4 years experience, involving project ownership and design. SDE-3 entails architectural leadership and mentoring. For IIT Bombay recruits, check specific job descriptions on company career pages; use IIT Bombay's alumni network to understand role expectations at each level.

Utilize IIT Bombay's placement cell workshops, alumni mock interviews, and resources like 'Cracking the Coding Interview'. Online, focus on LeetCode and GeeksforGeeks for DSA, and 'Designing Data-Intensive Applications' for system design. Join IIT Bombay coding clubs (such as FOSS or CFI) for peer practice and access to past interview questions shared on campus forums.

Expect fast-paced, ownership-driven environments with agile methodologies. Companies value IIT Bombay's rigorous training, so demonstrate adaptability, collaboration, and continuous learning. Be prepared for on-call rotations, code reviews, and feature development from day one. Research company values on their careers page and ask about team dynamics during interviews to ensure fit.
