TikTok Software Developer interview questions

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.
