Contacted by recruiter to schedule time. I replied promptly, but they did not reply until over 1 week later. As a result, I had to provide additional availability for the following week. We finally schedule something. Come interview time and they do cancel last minute. They contact me again for additional availability. I provide them with times again. No reply for over 3 weeks now. I'm just going to assume this isn't going anywhere. Out of all my 40+ interviews, I have never experienced such unprofessionalism. Pretty disappointed, especially from a company with such a big name.
