J'ai postulé via la recommandation d'un employé. Le processus a pris 2 semaines. J'ai passé un entretien chez TikTok (San Jose, CA)
Entretien
3 rounds in total. Every round will have deep dive on Resume, foundation questions, 2-3 Coding questions, BQ questions... Overall fair enough. Coding on their own platform. Might interview in Chinese sometimes.
First round of tech interview: 3 questions, 1 SQL hard, 1 SQL medium and 1 brain teaser. Interviewer asked to code in a notepad and insist my solution was wrong. As I couldn't run the code in IDE I couldn't prove my code was right. After my interview I ran my code and it is working perfectly well.
