GLG Senior Client Associate interview questions

Started off with a phone call, followed by phone interview with the manager, 60 minute case study, and last round constitutes of speaking with 3 senior level individuals Last round was a disaster, especially for someone who's interviewing for a role where no expertise is required as per job description, but seems like they want individuals with experience too...one of my interviewers seemed to be ready to leave the zoom meeting in like 20 minutes or less...shows how lack of care is given for the candidates

4 interview process; - 1st phone call was with the recruiter, all good and I was explained the role and it matched what I wanted and the job description - 2nd interview was a video call with a team manager - all went well and I was explained more about the role, team culture and structure - 3rd interview was a phone call with another team manager and here I was given a business case - 4th interview was onsite with two VPs after another. Here the role was described very differently and they could NOT recognize the role from what I was saying, nor from the job description I got rejected. I have spent many hours on preparation, setting up interviews and going through them, and then I think it is absolutely unprofessional that they do not give feedback but just say that I did not get the job. A company that says that they always coach and give feedback... well not such a professional company in the end in terms of how they treat people
