Hey @seanprashad just as a heads-up: I know your lists are curated from other sources, but might be worth looking into new sources as well. I've heard from people going through FB interviews currently that they've been told by recruiters that they will no longer be asking DP problems, and I've had this confirmed by other people who do interviewing at Facebook that they're seeing less "signal" from people around DP problems. Currently, DP problems are the second-most common tech challenge type listed from these combined sources on your site.
