TikTok Software Developer interview questions

This coding problem is quite challenging and requires a solid understanding of computer science fundamentals. It involves deep knowledge of algorithms, data structures, and possibly low-level system design principles. Tackling such a question demands both strong problem-solving skills and a firm grasp of core concepts like computational complexity, memory management, and optimization techniques.

OA and then Round1 and in this round it was a bit of resume stuff and then I was asked about a BFS Question and in the round 2 I was asked a trie based question but got rejected after doing well and dont interview for tiktok. Thank you
