There was a bit of a language barrier. It was hard to ask clarifying questions, they answered with "yes" or "no" answers when I asked them things like "What do you like most about working here" they responded "Yes I like working here" and offered zero help during the interview other than "you are wrong on this one". Seemed to only care about the most optimal solution. Interviewer was polite but if you're not international Chinese I would not recommend due to language and cultural barrier made it difficult to work with. I'm ABC btw

15 min of short answer about networking/databases then 30 mins on LC medium
Fiz uma entrevista na empresa TikTok (San Francisco, CA).
Entrevista
OA - 1 arrays Medium, 1 Trie Hard. I had 45 minutes to complete that. I was able to do the medium in about 15-20 minutes but I am not that great with trie ds so I was not able to finish.
Four Round Process
Phone Interview with Human Resources
Coding Round; 1 DSA Leetcode Medium Q
Coding Round: 2 DSA Leetcode Medium Q
Manager Round: System Design Q and behavioural Q
It took about four weeks from application to offer, longer than I initially expected. The initial phone screen was straightforward, covering my resume and some basic algorithms. Then came the technical rounds, which were challenging. One question on minimum window substrings had me diving into a sliding-window approach using pointers and hashmaps. Funny enough, I recognized it mid-round as something I’d practiced on PracHub just days before. After a final system design discussion, I received the offer and happily accepted.

Pergunta 1
Given two strings s and t, return the minimum window substring of s that contains every character of t including duplicates, or an empty string if no such window exists. Walk through the sliding-window approach using two pointers and a character-frequency hashmap, analyze the O(|s| + |t|) time complexity, and discuss how to adapt it when t contains characters not present in s or when s arrives as a stream that cannot be fully buffered.
