When confirming the date and time, I accidentally misspelled the interviewers name by one letter. Yes, I made a mistake and I understand that automatically disqualified me. However, if his condescending response is any indication of the culture of this company, my advice to you is to proceed with caution! I own my mistake and understand why they aren't moving forward with me. But his tone was offensive and I would never work for a company that speaks to their employees this way.
After looking up the interviewer on LinkedIn, I found out he would have been my boss. I am SO GLAD I dodged that bullet!!!
