I’m excited to recount the thorough interview process my friend experienced for a software engineering role at Oracle. This demanding journey was structured to evaluate a wide range of competencies.

Initial Aptitude Screening:

• Two-Hour Aptitude Test: The gateway to Oracle began with a comprehensive aptitude test, covering logical reasoning, statistics, data analysis, computer science essentials, and English language skills, all administered through the ProAptitude platform.

Sequential Technical Interviews:

Consecutive Rounds: Post-aptitude success, the candidate faced a trio of technical interviews, each homing in on distinct elements of software engineering expertise.

1. Round 1 (30-40 minutes): Kicking off with a coding challenge akin to the maximum subarray sum problem, this round tested algorithmic dexterity, followed by probing into Computer Networks, Operating Systems, and Python nuances, including a DSA query on binary tree diameters.
2. Round 2 (30-40 minutes): The second round placed the spotlight on the candidate’s command over the C language, particularly memory management, alongside discussions on Computer Networks, Operating Systems, academic projects, SQL optimization, and the nuances of C++.
3. Round 3 (30-40 minutes): The concluding technical dialogue shifted to a more conversational tone, exploring scenarios related to cloud services, big data, and database optimization, with the candidate demonstrating knowledge in MATLAB, Java Spring, and cloud solutions.

Outcome:

Internship and Full-Time Offer: The culmination of this rigorous process resulted in an offer for both an internship and a full-time position.

Preparatory Advice:

Candidates are advised to thoroughly prepare across various domains, articulate their problem-solving approach, showcase C language mastery, practice Oracle-specific DSA questions, and maintain confidence with clear communication.

This narrative serves as a testament to the importance of all-encompassing preparation and the ability to adapt during the intricate interview processes at renowned companies like Oracle.
