Pro Tips for Choosing Your Topic

• Avoid the 'I built my first PC' cliché; focus on the logic and problem-solving aspect of that experience instead.
• Connect your personal projects to specific computer science theories (e.g., mention 'Time Complexity' when discussing a script you optimized).
• Show, don't just tell, your passion by referencing specific papers or researchers that have influenced your worldview.
• Narrow your focus to a specific niche (like Cybersecurity or HCI) to demonstrate depth of interest rather than a surface-level overview.
• Discuss a time a piece of code failed and how you used systematic debugging to find a solution—this shows resilience and methodology.
