They are generally proactive about inviting you to interviews.

What they said on the phone differed from what they said in the in-person interview. For the second interview, they promised to inform me of the location and time, but in the end, I had to call and ask the day before, only to be told that it had been canceled or that they wanted to refer me to another job. Then, if I showed even slight hesitation when being introduced to a job, they would hang up. The quality of the recruiters was astonishing.
