可能康嫂不认真或者闭只眼；好的康嫂推荐信重要，人品特质自己吹不到位. 有些进大学时还没发表或奖项只有推荐够到历年留的位

不管成就如何，推荐重要.

现在进公司还有“backdoor check”：

The practice of a company checking a candidate's references or work history without the candidate's explicit permission is generally known as a "backdoor reference check". These are also referred to as "informal checks," "quiet checks," or "back-channeling," and involve contacting individuals known to the candidate.

"Labs like @OpenAI also hire researchers straight out of undergrad, like @kevin_wang3290, though the bar is high. Kevin was highly recommended by his advisor and was first author on a NeurIPS 2025 paper. There's a lot of bad NeurIPS papers, but we could tell this was a great one. (Indeed, after he joined OpenAI his paper was one of 4 out of 5,290 to receive a Best Paper award.) His advisor's recommendation counted for a lot because it can be hard to evaluate a researcher just based on a resume or even a paper."
