Not OP but similar level of experience.

I had the leet code once, interviewing for Meta. I didn't prepare because I thought that it was pointless, but I was curious about what it would be like to do it. So, I went through with it and to my shock and awe I managed to do it. The feedback was that I didn't ace it but I did more than well enough for the interviewer.

I didn't get the job though. The last step was a really strange and uncomfortable 1-1 chat with a "very senior employee". This did not go well.
