Wits Solutions interview questions

Was called out of the blue at 5pm about a position. I was asked questions that are all clearly already answered on my resume if someone took even 2 minutes to look at it. When asked my salary expectations, they were met with an actual grunt and then replied if i was willing to negotiate lower. For their manager position, they are looking at a bargain basement salary. I was then asked if I would be avail after 6pm (same day) to speak w a manager. When I answered "no", the person was very rude with a "well why not". I then proceeded to give my schedule when I would be available. Later that evening i emailed and withdrew my name from being a candidate. The next day, one of the managers called me and said he wanted to call me anyway even though he saw that I withdrew. Keep in mind he called me outside of any of the times I had even previously said I would be available. Both the manager and the initial caller both had aggressive attitudes and were highly unprofessional. Avoid dealing with them at all costs!!
