Entrevista
The position was for ad-sense as a computer vision engineer. I was able to attend two rounds of 1 on 1 interviews. Each interview consisted of three parts.
1. They discussed my projects based on resume and how much I know about deep learning
2. Their work needed mostly object detection. So this was technical info about object detection algorithms. I had prepped for this for the second interview. For the first one, I answered on the basis of my experience
3. A leetcode medium DSA question

Pregunta 1
Explain YOLO and F-RCNN? Then further went into detail about the ROI pooling layer.
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.
