Building a Long-Term Career in Data Engineering – Seeking Insights

Recently switched to a remote data engineering role with 6 years of work experience and after working at Goldman Sachs. My goal is to prepare for FAANG/MAANG opportunities and build a long-term career there. Curious if they offer remote roles, as I’m not sure about their presence in Pune. Also, I’m planning a structured upskilling roadmap—how much time should I dedicate and which skills should I focus on to crack these interviews?
