All along: 一直
一直 (yìzhí) means "continuously / all along" — an action or state that hasn't stopped: 我一直在这家公司工作 "I've been working at this company all along", 昨天一直在下雨 "it rained nonstop yesterday". It goes right before the verb (or before 在 + verb).
Don't confuse it with 总是 "always" for habits: 他总是迟到 "he's always late" (happens every time), vs. 他一直在等你 "he's been waiting for you this whole time" (one unbroken stretch).
