The interviewer called 15 minutes late and apologized. Was friendly at first but once the person found out that I was unfamiliar with specific software applications (none of which were even mentioned on the job description or job requirements), was suddenly belittling me for being inadequate and was no longer interested to talk to me. If the interviewer would have spent time reading my resume, they would have found out that I was unqualified and would have saved both of our time.
