Google decided to call me back ASAP and skip phone screens for me and go straight to the onsite, and I scheduled my onsite as late as possible and it's 3 weeks from now. They told me there will be no system design at all on the interview, so I am only preparing for ds&a.
The problem is I learned that I'm REALLY bad at this. I've been trying to get down 4 hours a day of studying, and I take anywhere from 5-30 minutes to solve easy, and many times I can't even solve a medium in an hour. Most of the mediums I've done I try for an hour, fail, and end up just reading a solution. I've solved a handful of mediums on my own, but not many. Hards? Forget it.
I'm in a really bad spot right now but I don't know how to get myself out of this. I don't know how much or what I'm supposed to be studying. I don't know if I do as many mediums a day as possible, if I should be doing easy, if I should be doing hard.
Tl;dr I can barely solve a medium and I have 3 weeks to get ready for a google onsite. This seems like an impossible task.
