Obsessed with FB data scientist role!

I really want to hear from FB data scientists! For some reason, I think working at FB as a data scientist would be really great for me. I’m not happy with my current TC and don’t see a bright future for the disk drive industry. Also, there is literally no room to grow in my current organization. Current salary/bonus/rsu ~ 142/25/25 Education Physics PhD, Math MS. YOE ~ 15 yrs I mostly do data analysis of test data to understand magnetic recording physics to help product development. I use SQL/Python for data manipulation, summaries, presentations, and JMP for data exploration and analysis, switching to Python more and more. I feel very underpaid with no prospects for growth. Yep that’s life in hardware industry, and a dying one like disk drives. I stay with my current company because my commute is 10-15 min each way, like my coworkers, and the work is interesting, except the low pay an no opportunity for growth. I visited FB campus once and really fell in love with it. I like social media and think of FB as a great company. Am I wrong? I also think even as level 4 I would get a significant boost in pay. But preferably level 5 would be ideal. Is my impression that level 4 TC ~ 275 and level 5 TC ~ 320 a pipe dream? FB data scientists, please share information and help me out. First what’s TC for level 4 and level 5 in the analytics team (not core machine learning or infrastructure). How should I prepare for the interview? Is working at FB as a data scientist really all that great? Please share information with relevant details. Thank you! BTW, I’m a citizen and don’t need visa sponsorship. Comments from data scientists at Google and other companies are welcome too.
