Transition to Big Tech as Mid-Level Fullstack Developer

This individual, with 4 Years of Experience (YoE) as a Fullstack Developer, is well-positioned for a mid-level role at a 'big tech' company. Their existing experience in small teams can be framed to highlight broader impact and end-to-end ownership, which can be a strength. The path involves rigorous preparation in core computer science fundamentals (data structures, algorithms), system design, and behavioral interviewing. Key skills to emphasize include proficiency in relevant programming languages (e.g., Python, Java, JavaScript), web frameworks, cloud platforms (AWS, Azure, GCP), databases, and CI/CD. Targeting companies like FAANG/MAANG or other large tech corporations for Software Engineer or Fullstack Developer roles would be a suitable direction. They should focus on interview prep resources like LeetCode and System Design Interview guides, and update their resume to reflect scalable solutions and impact.
