I have applied throgh naukari.com and got call from HR. I have attended interview in oracle office. They took 4 round in office and then they have told to have call from US after that i have attended 2 calls from US and post that they took one more telephonic round from India. After all this HR called me and told that all feedback is positive and had salary discussion and told that he is going to send this for HR approval. He called me after one week and told me that HR has given approval and he is going to this for final approval and meanwhile I will get background verification but nothing happened 1 week and then I called to HR and he started telling me that he has negative feedback from US. They have wasted my 1 and half month. they don't have curtsy to tell proper feedback and he said he will refer me to another opening after 2 weeks letter he called me and said can you give interview for another job i agreed and has given interview but now HR guy have not come back any kind of feedback. If they don't want to give high salary then why they call for interview and even don't have proper curtsy to give proper feedback. It's full waste of time to give interview in oracle. I had very very bad experience. No formal curtsy to give proper feedback.

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.
