GLG interview questions

I applied online on a Sunday afternoon and got an email to set a phone interview the next day. The interviewer was the senior survey associate and he asked me several behavior questions based on my resume and a little bit about GLG.

GLG and the recruiter I was working with, are completely unprofessional. I would mention their first name but glassdoor prefers to sensor reviews. GLG ghosts candidates after stating they would like to move forward. I had a phone screening with the recruiter. Then I had an interview with the hiring manager that went really well. The recruiter emailed me saying she wanted to schedule a second round with another member of the team. I responded. No reply. I follow up, no response. Completely unprofessional. However, they were paying below market so there is no love lost there.
