The OA felt standard, but the onsite was tougher than expected. I tripped up during the live coding round—even though I had done plenty of LeetCode, solving under pressure was different. Looking back, I wish I had done more mock interviews or reviewed real interview flows ahead of time. Platforms like Hack2Hire can help simulate that pressure and show you what kinds of questions actually come up, especially for companies like TikTok.

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.
