I know this post is no value add to some, but please do not down vote. I have been preparing on DS & Algo since May (was on and off earlier, but became regular on leetcode from May) and I have google interview in a month but I am still not confident. I can come up with only sub-optimal solutions, but sometimes fail even doing that and end up visiting the discussions. However I am able to grasp the solutions provided quickly and also able to solve related problems. Need help to decide if i should give the interview ? I have a month more what all should i be prepared with to face the interview.
