They called me out of the blue in the middle of a work day and asked if I was available in 20 minutes for an interview. Then they said I would an email confirmation. I waited for a few minutes and didn’t receive it. They called me again and I answered. They asked what my minimum salary requirement and then said they could not meet it. I offered lower and they said no to that. Then they just sort of said okay and hung up. Highly unprofessional do not recommend.
