Suppose I have an offer in company A and company B asked me to interview before. Should I call company B voluntary that I wouldn't come to interview? Is it non ethical that doesn't attending to interview sliently? (I fear I will be blacklisted elsewhere!)
Note: my question is different from Should I go to an interview I don't intend to accept the job (if offered)?: those question is about whether I should go to an unwanted interview, but in my situation, it assumes I already given up the unwanted interview, and I want to focus on the consequence of missing interview without noticing the company, instead of the value of unwanted interview
