How is that a good thing? Of course, in a startup you can't have everything - but that doesn't change the fact that in startups the employees often share a great deal of the risk (in opportunity cost) and don't get rewarded in the same scale when it all works out. Worrying about money, especially in times like these, is perfectly natural.
And quoting somebody's email verbatim, without permission? That shows a lack of class (it's really that rude), but worse, it shows a lack of -judgment- because Auston should know he can't gain anything by ridiculing somebody's cover letter and grammar mistakes.
Don't get me wrong. I do agree that a hurriedly written cover letter that only focuses on the salary should land the resume on the no-hire pile. But why attract negative publicity to your own company? I don't get it.
