Basically title, new grad swe role in US, did the neetcode 150 a couple months ago but didnt really absorb much of it. Ive redone and understood all the problems up to trees so far (42 problems) but I still have 11 more topics to go (110 more problems) and i definitely dont understand dynamic programming at all as of now. I want to try and hit 50 tagged as well. I have leetcoded almost every second I can but I dont think my current pace/ understanding is going to be enough Should I push the interview back to the week of April 27th or will they run out of headcount by then?
