Unless you view it as not worth the effort.

I've done two onsites with Google in the past essentially YOLOing it (I only study my interview failures because I view otherwise as an inefficient use of my time) - first time did terrible, second time almost passed if I didn't completely bomb my very last session. The second time ended up not really mattering because two different teams in two different orgs for my current non-Google FAANG wanted to hire me after onsites done on back to back days (side note: that was almost 15 hours of interviewing in two consecutive days - that's a lot of time, I only was able to do it because I was funemployed at the time).

I actually appreciate it very much if a candidate didn't study & focus more on giving the best answers to their capability when I interview them - the questions I give them are usually questions that no amount of studying would have prepared them for, so already taking the mindset of trying to respond thoughtfully & earnestly to problems & situations that change on a whim puts them a step ahead.
