GLG interview questions

I applied for this role and had a standard phone interview (ran through my background, CV and expectations) which went pretty well, in my opinion. Few hours later, I got an invitation and instructions to the second round, a case study, which I replied to with available time slots as they asked. Day after that, i got an email that they are "pausing" my application for this role due to an overwhelming response from candidates. Instead, they attached a link to another position they were hiring and asked me for available times for a phone interview, now for this new role. After replying to this email with my time slots, I never heard from them again. Very unprofessional!

Met with 4 different team members over a span of 1 hour (about 15 min apiece with each team member. This was following a phone screen about a week prior.
