TikTok Frontend Developer interview questions

Was reached out by an HR representative via WhatsApp. She was incredibly helpful in coordinating all the interviews and even provided resources to help me prepare for the technical interviews. Skipped the initial OA, and the interview processes comprised three technical interviews and one HR interview. During the first round of interviews, I was asked about the fundamentals of HTML, CSS, and JavaScript. It was really insightful as the interviewer took the time to explain concepts whenever I needed clarification. Questions that he asked, including: - The different types of basic data types in JS, some questions regarding let, const, var, and this - Categories of HTML tags, differences between and elements - The box model in CSS, code in CSS to - Explain the concepts of classes and functions in JavaScript - One math question: horse race problem, etc Overall, it was a valuable experience, and I appreciated the interviewer's patience and willingness to help me understand the concepts better.

Many actual implementation of React.js and JavaScript questions, as well as some optimization scenario in web application. Asked a lot about my past project and work experience. I would say it is an intense interview for me.
