Hi everyone,
I have around 6 years of experience in Python, AI/ML, NLP, and Generative AI. I am planning to prepare seriously for interviews at companies like Google, Microsoft, Amazon, and other product-based companies.
I would like recommendations for: Best DSA (Data Structures & Algorithms) courses/institutes Best System Design courses (Low-Level & High-Level Design) Online vs Offline coaching experiences Structured interview preparation programs Mock interview platforms Roadmap for experienced candidates , Could you please share your experiences and suggestions regarding:

1. Which course/institute helped you the most?
2. Is coaching really worth it, or is self-study sufficient?
3. What resources would you recommend for someone targeting FAANG-level interviews?

Thanks in advance for your guidance!
