I want to apply for a senior role at a company known for giving LC Medium coding interviews, but I'm absolutely terrible at coding challenges despite years of professional experience. I've been at this day after day for a couple of weeks and am embarrassed to say that it still takes me about an hour to do an LC Easy question and about a day (much of which is in a state of writer's block) for an LC Medium question. I'm already starting to feel burnout and yet am worried that I'm not going fast enough or that I'm doing something wrong, so I'd like to see how long it took others to get comfortable at LC Mediums? Thanks in advance.
