The SWE Interview Process
The Software Engineering (SWE) interview process is notoriously rigorous. Whether you are aiming for Frontend, Backend, or Full-Stack roles, the typical interview loop at top tech companies involves 4 to 6 rounds of intense technical and behavioral screening.
Typical Interview Rounds
- Recruiter Screen: A brief 30-minute chat about your background, expectations, and visa status.
- Online Assessment (OA) / Phone Screen: A 45-60 minute coding round focused on Data Structures and Algorithms (DSA) over a shared editor like HackerRank or CoderPad.
- Onsite Loop:
- 2x Technical Coding Rounds (Medium to Hard Leetcode problems)
- 1x System Design Round (For mid-level and senior candidates)
- 1x Behavioral / Culture Fit Round
How to Prepare for the SWE Loop
Acing the SWE loop requires balancing your time between algorithms, system design, and behavioral preparation. Do not make the mistake of only studying LeetCode while neglecting your behavioral stories.

Practice SWE InterviewFrequently Asked Questions
How many LeetCode questions should I solve before an interview?
Quality over quantity. Solving 75-150 problems that cover all major patterns is much better than memorizing 500 random problems.
Does the language I code in matter?
For general SWE interviews, no. Use what you are fastest in. However, for specialized roles like iOS engineering, you will be expected to use Swift.
