Date of Interview: 12th April 2024

Interview Rounds:

Technical Screening: The interview process commenced with a technical screening round where I was evaluated on my programming knowledge and problem-solving skills. The interviewer inquired about my experience with various programming languages and requested details on specific projects I had undertaken.

Questions Asked:

• Elaborate on the distinctions between object-oriented programming and functional programming.
• Describe a challenging technical issue you encountered in a previous project and how you resolved it.
• Code a binary search algorithm and analyze its time complexity.

Technical Interview: In the subsequent technical interview round, I engaged in an in-depth discussion with a senior software developer at Deloitte. We explored my software development expertise, including familiarity with different frameworks and tools. The interviewer presented me with a coding problem related to data structures and algorithms.

Questions Asked:

• Detail a project where you implemented a complex algorithm and optimized it for performance.
• Explain your approach to debugging and troubleshooting code in a team setting.
• Write code to reverse a linked list and elucidate the logic behind your solution.

Coding Challenge: Following the technical interview, I participated in a coding challenge where I was tasked with solving a real-world scenario using object-oriented principles. I designed a solution on a whiteboard, showcasing my problem-solving abilities and coding proficiency.

Questions Asked:

• Design a class hierarchy for a banking system encompassing accounts, transactions, and customers.
• Implement a sorting algorithm and discuss its efficiency compared to other sorting techniques.
• Explain the concept of polymorphism and provide an example from your coding experience.

Advanced Technical Round: Subsequently, I encountered an advanced technical round where I faced medium-level Data Structures and Algorithms (DSA) questions and puzzles. The interviewer assessed my analytical thinking and problem-solving skills with complex scenarios.

Questions Asked:

• Solve a medium-level DSA question involving tree traversal or graph algorithms.
• Discuss a puzzle or brain teaser to evaluate logical reasoning and creativity.
• Implement a data structure such as a priority queue or hash table and explain its application in a real-world scenario.

Outcome:

Despite showcasing my skills in the advanced technical round at Deloitte, the competition was intense, and I was not selected for the Software Developer position. While the outcome was not as anticipated, I valued the opportunity to engage with challenging DSA questions and puzzles, gaining valuable insights into the technical expectations at Deloitte.
