+1000% Even doing all the LC problems tagged Meta is severely missing the point. It can work for some people if you get a little lucky, but the interviews are not about doing LC.
I worked at Meta for 8 years, did 400+ interviews, and helped craft the Product Architecture style type.
I wouldn't be disappointed but I would also reset how you prepare for the real deal.
Being "close" doesn't count much at Meta because they are looking for "clean thinking". This is also why they do whiteboard-style interviews still instead of compiled code. If your process is muddled and jumpy then being close won't matter. If you haven't seen a problem, get a little lost and take a long timer, you can still pass by having clean and clear thinking and getting a reasonable solution out. You own't pass by scrambling and jumping around to a half baked optimal one.
