GLG Senior Associate, Strategic Projects interview questions

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.
