Interview
Have a talk with the team member about a lot of the questions about Apache Spark. There is a lot of background project review and Spark tuning-related questions. You really need to understand the spark partition and how does system works.
Interview questions [1]
Question 1
Spark tuning-related questions, like broadcast join and what happens when you join a large data set into many small data sets.
Not smooth, HR screening was smooth but later interviewed by keep asking somehting i wasn't really understand. Overall experience wans't good. Hope I meet other nicer recruiter next time. That's the reason I give a down thumb on this experience.
I applied through an employee referral. The process took 2 weeks. I interviewed at TikTok (San Jose, CA)
Interview
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.
