One of the worst interviews in my life: I was interrupted in the middle of the interview and was told that I did not pass it as they had candidates with better skills and experience. It was mentioned with the tone showing the HR's dominance without any respect to the candidate. I find it very unprofessional.

Phone Interview, In-person Interview, Project that I was given little guidance on, then a final interview with the marketing manager. In all three interviews (one phone, two in-person) they were late by 5-10 minutes. That should have told me enough right there. When I was not given an offer, I received an email that the recruiter clearly copied and pasted to every applicant, despite the fact that I took two separate days to visit the company, and spent three hours on their bogus project.
