> Because [arriving 15 minutes late to a 30-minute interview] was [nothing]. I'd expect over 95% of both interviewers and interviewees to say that arriving 15 minutes late to a 30-minute interview is very much not nothing; it's a serious breach of what is expected – on both sides of the interview. If you show up late for an interview, no matter which side of the table you're on, you ought to apologize and, if you're more than a few minutes late, have a good explanation. To do anything less signals that you are an unreliable person. And, when you are representing a company, it makes the company look like it's run by people who don't even understand how to do something as simple as show up on time. It suggests that one of the company's unspoken core values is Dysfunction.
