TikTok Software Developer interview questions

Asked about javascript, react, performance improvement. Deep dive into the resume. Talked about the past projects. Any challenges and how to solved. Leave around 20 mins to code. One is about javascript's async/promise and the other one is object operation.

Difficult interview to pass because they ask tough questions (as most large companies like this do). Especially for an intern position, the difficulty is comparable to the real deal position. Recommended to practice a lot.
