I applied online. The process took 3 months. I interviewed at TikTok (Seattle, WA) in Oct 2023
Interview
It was a four-round interview process over a period of three months. The first round involved coding exercises similar to those found on LeetCode. The second round assessed knowledge of machine learning basics and statistics. The third round focused on discussing work experience and machine learning system design. The fourth round, with the hiring manager, included further discussion of work experience and a LeetCode-style problem. Despite excelling in all four rounds, they ghosted me.
