GLG Senior Research Associate interview questions

Extremely unprofessional - if the HR/recruitment is anything to go by I would highly recommend avoiding the company. Contacted initially via LinkedIn, I had one phone interview (laughably aggressive and undermining questioning) and one video conversation (fairly pleasant), followed by an invitation to come interview at the company. The company has invested recently in a new office around oxford street/fizrovia which gave a good first impression, however, this was soon altered. Although I had been given a complete itinerary of which five individuals I was going to be meeting in advance, the interviews changed and two end up not having time to interview. Competency of the interviewers were mixed, although very awkward communication and interaction skills given what the company does. Never heard from the company again.
