I will throw out counter-experience that I did not succeed at technical interviews until I treated it like a fulltime job. In the past I just brushed up and failed Google's interview a handful of times before I decided enough was enough.
My takeaway ultimately is that how much time and effort one chooses to put in is entirely personal based on how much they want one of these jobs + what their gaps are in algorithms and data structures. Some people are going to need more effort than others.
