TikTok Frontend Developer interview questions

I had 2 rounds of technical interview with members of the team. First round included a fundamentals sections for 40 mins with questions on memory allocation, image storage, networking and general introduction. The second half was a LC Medium. Second round consisted of another similar fundamentals section and another LC Medium. As this was a Mobile engineer position they asked questions related to mobile development after I had already mentioned that I do not have relevant mobile experience but have done web development with some tangential projects for mobile. As this was a graduate opening, I did not understand their stance of requiring experience in the exact mobile software/frameworks they used, which can be learned fairly easily on the job after already having some development experience.

Applied online then OA. First round DSA -> Frontend coding -> hiring manager round. OA is not automatic, you must pass resume screen before. This also varies highly based on team. The team was overall very polite and I enjoyed every interview even though I got axed in the final. The recruiter didn't even have the courtesy to send more than an automated reject email after 3 rounds though.
