I applied online. The process took 2 weeks. I interviewed at TikTok (Singapur) in Oct 2023
Interview
They send you a Hackerrank test to do in a short time, few question but ranges a lot of domains not even related to the job proposed. Some questions can be very hard to do.
Questions on code signal. Will ask question about Unix, SQL, and programming. The site was easy to access and plenty of time for the assessment. However, questions may be confusing and have to make sure that code signal's test cases are running. In my incident, had some issues with the test code.
Tech round (45 minutes): I was given the requirements. Then I was asked to come up with edge cases, give an overall idea on how the algorithm should be implemented. After my implementation, not much time is left for optimization. But still, I made some comments on the possible routes.
