I got my first round of data engineer interview with TikTok soon. Any source of recent SQL + LC questions?

Inb4 all the tiktok/China comments I got 0 help here related to tiktok. Any other company sure, but good luck getting advice related to tiktok. Just random hate lmao I wish I could help but I did SWE

I attended their interview and flunked hiring manager. They asked me 1) lc hard 2) 2 sql mediums 3) data engineering Sys design 4) get to know me style behavioral questions in hiring manager round
