Ho presentato la mia candidatura online. La procedura ha richiesto 3 settimane. Ho sostenuto un colloquio presso TikTok (San Francisco, CA) nel mese di ago 2023
Colloquio
Initial HR call where questions are around your resume. After that I got a phone screen with a Data Engineer at Tiktok which was ok, there were questions about my previous experience, data modelling and spark architecture. The interviewer's english was not great, so I couldn't get any hint even though they were trying to help.

Ho presentato la mia candidatura tramite segnalazione di un dipendente. La procedura ha richiesto 2 settimane. Ho sostenuto un colloquio presso TikTok (San Jose, CA)
Colloquio
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.
