TikTok Machine Learning Intern interview questions

just finish online OA. The online OA happens on hackrank and there is an interviewer spying on me... I am not able to debug just write your code and guess whether it works

I interviewed in Jun 2021, pretty expected questions nice interviewers logistic regression, SVM, Leetcode questions, brain teasers, hypothesis testing, probability problem, business analysis questions, A-B testing, ad loads rate, gradient descent
