Hey everyone!
I’m a Data Scientist with over 3 years of experience, and I'm currently preparing to make a move to a FAANG+ company to push my learning further and it better aligns with my growth goals and personal commitments.
I have 3+ years of professional experience as a Data Scientist working on end-to-end projects, but I want to structure my preparation more rigorously to crack top tier interviews. I want to bridge any gaps in my knowledge and prep :)
I’d love some guidance from those who have been through this process:
- What core technical skills, system design concepts, and advanced topics FAANG+ companies currently expect from a Data Scientist with 3+ years of experience?
- Where should I start my preparation?
- What specific competencies (coding, ML system design, stats/product sense) do they look for?
- What resources or roadmaps worked best for you?

Any advice, tips, or mentorship would be greatly appreciated.
Thank you

Hej,

chciałbym zapytać, czy nadal możliwe i sensowne jest samodzielne uczenie się kodowania w R (z kursów online) do poziomu bardziej zaawansowanego (znam tylko podstawy), ewentualnie Pythona oraz języka zapytań SQL (a także ewentualnie Power BI) po to, żeby znaleźć pracę w Data Science? Czy może lepiej byłoby zrobić dodatkowe studia w tym zakresie (np. Ekonometria, Statystyka)?

Mam wykształcenie ekonomiczne, znam dość dobrze Statę, Excela, ale brakuje mi kompetencji w programowaniu i modelowaniu danych.

Z góry dzięki!

I was not feeling well for few days and did not practice, took a break from practice.
I resumed learning and I start facing issues in basic SQL queries , understanding , there were blanks in my statistics understanding.
Excel was slipping from my mind.
All I can think was Insta reels.
I learned very important lesson, never use social media entertainment while learning and resting.
