GreyCastle Security interview questions

Had 3 different calls; call with the recruiter, but she forgot about it and after 15 minutes of waiting I finally emailed her and she said let's reschedule. Fine. Had that call, went great. Moved on to round 2 with the Senior Director of Business Development. That call went great and he mentioned, "If we decide to move forward, the next call would be going over the job description to make sure you fit and talk about compensation". Was ecstatic to find out I was moving on to the next step. Call 3 was the opposite of what I was told it was going to be. It was another full-blown interview, which I was not prepared for. I tried calling the recruiter's direct line multiple times to talk about that call as it did not go how I imagine and wasn't able to get ahold of her. This was pretty disrespectful to me as I had prepared to talk about how my qualifications met what they were looking for, but due to a lack of communication on their part, I was completely blindsided. The reviews on Glassdoor about the lack of communication from the recruiters are absolutely true. I would steer away.
