Deep Dive into Evaluation Areas

Technical Proficiency

This area is the bedrock of your evaluation. You must demonstrate that you can write production-ready code and understand the underlying mechanics of your preferred language.

Be ready to go over:

• Memory Management – Specifically in languages like C++, ensuring you understand resource leaks and lifetime management.
• Data Structures – You will likely be asked to implement or manipulate structures like trees, lists, or stacks.
• Language Internals – Be prepared to explain how your primary language (e.g., Java, Python, C++) handles concurrency or memory.

Example scenarios:

• "Write a function to reverse a linked list."
• "Explain how you would optimize a slow database query."

Architectural Vision

Interviews often move from code-level tasks to system-level thinking to see if you can contribute to long-term product health.

Be ready to go over:

• Scalability – How your code behaves when the number of users grows by a factor of ten.
• Security – Best practices for keeping data secure within an application.
• Framework Mastery – Deep dives into libraries or frameworks like QT, Angular, or Spring.

Example scenarios:

• "How would you design a system to handle high-concurrency requests?"
• "What are the security implications of this specific code implementation?"
