Pgrammer is built for technical interview preparation, and its design choice is to give hints rather than solutions. That distinction matters more than it sounds: a candidate who reads a model answer learns the answer, while one who receives a nudge and then solves it themselves builds the reasoning the interview actually tests.
Personalised learning shapes which problems appear next based on performance, which is the advantage over working through a static problem list. Most candidates over-practise what they already handle and avoid their weak areas, and adaptive selection corrects that tendency.
At around twelve dollars a month it sits well below the cost of interview coaching, with a free trial to assess whether the hint style suits how you learn. It is preparation-specific, so its usefulness ends when the interviews do.
