Solicité el puesto a través de la escuela superior o la universidad. El proceso duró 1 semana. Acudí a una entrevista en TikTok en jun 2025
Entrevista
the interview process typically includes an initial conversation to learn more about the company and role, followed by a technical round focusing on SQL, Python, and product analytics case questions, and a final discussion assessing problem-solving and communication skills
A former colleague referred me to the Data Scientist position at TikTok, which kicked off the interview process. The technical screen included a question about designing an A/B test for a ranking model, followed by an SQL challenge related to user sessions. The funny part was that the SQL problem was a twist on one I had been grinding through on PracHub just a few days prior. After some behavioral interviews, I received an offer, but ultimately decided to decline as it didn't align with my goals.

Walk me through how you'd design an A/B test for a new ranking model on the For You feed, and how you'd pick guardrail metrics.
Given a sessions table (user_id, session_start, session_end, country), write SQL to find the users whose average session length grew the most week-over-week.
