Greif interview questions

Phone call from HR they gave a basic job description and asked was I still interested. Few days later he called back with a date and time to interview. He said I would meet with one person . It was a group of people that really threw me off never have had multiple interviewers at once. I could tell from expression I was going to get position. Of course they had to interview others. Next day I was offered job but all the paperwork and background checks took almost two weeks to complete. I was offered one amount in writing and paid lower amount It was corrected but the supervisor was not happy at all

I applied through the job board of my university. As the vacancy description was vague (they described several assignment, they did not say what you would actually be doing), I contacted the recruiter through Linkedin to ask some questions about the role. I was told they do not connect with prospective candidates before screening them. The interview was a screening, it took 30min and was through skype. It was poorly structured (e.g. I was not told what to expect) and more of an interrogation than a discussion. I was asked to describe parts of my CV, my motivation, what I would like to learn in this role etc. (standard questions). The interviewer had a rather arrogant attitude and questioned my answers. I was rejected 2 days later due to lack of fit and I asked for some feedback. It was then clear that any questions or contact with the recruiter beside the bare minimum for the recruitment steps is strongly unappreciated. Through the feedback I received, I have the impression that my being pro-active in gathering information about the role was actually regarded as a weakness and they prefered someone who would go hear-first in total darkness.
