Suggested Approach

Structure your resume walkthrough as a narrative that highlights 2-3 key projects, focusing on the technical decisions, trade-offs, and results. For each project, briefly describe the context, your specific actions, the challenges, and what you learned, ending with what you'd do differently. Tailor the story to emphasize adaptability and technical trade-offs, aligning with Bytedance's values.

Pro tip: Quantify results and trade-offs with metrics (e.g., 'reduced latency by 30% at the cost of 10% more memory') to demonstrate impact and engineering maturity. Also, show self-awareness by acknowledging mistakes and how you've grown from them.
