I applied online. The process took 1 week. I interviewed at TikTok
Interview
After the recruiter call, there are 4 rounds. 2 rounds per day. Questions are around SQL, python and big data proficiency. Working knowledge of big data technologies such has hive, spark, etc. is a must.
Interview questions [1]
Question 1
SQL: leetcode medium to hard. Schema/data sample is provided. Queries will require revisions based on interviewer follow ups. Python: leetcode easy to medium. It is important to clarify all the details before attempting to write any code. Additionally, space and time complexity analysis is required. Big Data: basic knowledge and project experience.
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.
