1. Initial Coding Screening Round (HackerRank) Format: Online assessment through the HackerRank platform. Number of Questions: 2 coding problems. Difficulty Level: Medium to hard. Focus Areas: Data Structures and Algorithms. Optimized problem-solving under time constraints. Objective: This round serves as an initial filter to assess the candidate’s core programming and algorithmic skills. Candidates who successfully solve both problems or demonstrate strong logic and efficiency move on to the next phase. 2. Loop Interview (4 Technical & Behavioral Rounds) Candidates who clear the screening round will be invited to participate in a loop interview, consisting of 4 back-to-back rounds. Each round is approximately 45–60 minutes. Round 1: Coding Interview (DSA – Trees Focused) Format: Live coding with an interviewer. Topic Focus: Data Structures and Algorithms, especially Tree-based problems (e.g., Binary Tree, BST, Traversals, Recursive logic). Difficulty: Medium level. Skills Assessed: Logical thinking Code correctness Space-time optimization Code readability Round 2: System Design (LLD + HLD) Topics Covered: Low-Level Design (LLD): Object-oriented programming principles, class design, and real-time implementation patterns. High-Level Design (HLD): End-to-end architecture design of a Medical System. Expectations: Clear articulation of component interaction. Handling scalability, reliability, and performance. Use of appropriate design patterns and technologies. Round 3: Bar Raiser Round Focus: Behavioral and situational judgement. Purpose: To assess the candidate’s attitude, problem ownership, collaboration, adaptability, and leadership traits. It may also include situational problem-solving and conflict-resolution scenarios. Note: This round is crucial for gauging cultural fit and long-term potential within the team and organization. Round 4: Hiring Manager Round Primary Focus: In-depth discussion on Medical System Design. What to Expect: You may be asked to improve or iterate over the design you provided earlier. Justify design decisions with trade-offs. Discuss past experiences in building or designing similar systems. Questions about team collaboration, project challenges, timelines, and ownership. Objective: The hiring manager evaluates not only your technical design depth but also your alignment with the team’s vision and project needs.

First based on my resume I was shortlisted for an interview and then I got a call for technical rounds. There were two technical and one final HR discussion round was there. After one week of that, I got an offer letter.

I had one technical interview for one hour and then 5 more interviews all in one day as an on-site interview. The overall interview was easy and friendly. If you study leetcode questions you will be able to answer all of them.
