Transitioning from Banking to Tech

I’m currently looking to transition from my data scientist role in banking (2.5 years of experience) to Big Tech (FAANG or FAANG-adjacent). How difficult is the switch, and what steps should I take?

Right now, I make $130K base + $20K RSUs + $32K bonus, but I’ve heard FAANG salaries are in the $250K–$300K range, which is a big motivator. On top of that, the tech stack at my current company is outdated, and I’m worried it’ll limit my career growth down the line.
