>> Everyone is busy, that's a terrible excuse not to brush up on your interview skills. I believe that their approach is arrogant, they just don't value candidates time.
I have a confession to make, I spent some time at Google. And after I left I was interviewing people using their approach and I regret it now.
P/S/ When you interview for a company, you actually taking more risk that the company (talking about folks who are headhunted into interviews). If it doesn't work out, you will be out searching for a job, you career growth may be slowed down. And what is the company risk?
