I applied online. I interviewed at TikTok in Dec 2020
Interview
this is a completely new OA for 2021. The questions are time consuming. Make sure you are very familiar with the language you use for the test. The test cases are tricky, don't expect to pass all of them, just move on to next question if you get stuck in one.
