I have interviews coming up at the end of February with Amazon and Facebook. I just paid for Premium, so I have the Top 50 lists. How likely is it that I would get questions from the company specific Top 50 lists?

I am interviewing for highly Experienced level positions.

I am trying to decide if I should work through all of those questions for both companies, some other collection of problems, or if I'd be better off focusing on studying algorithms or something else and just do a couple of problems a day.

I also am going to work through the Behavioral stuff.
