Analytic Partners interview questions

Interviewed for the NYC office for a summer intern analyst position. First step consisted of a phone call with HR rep, and then an in-person day of 4 different interviews with employees at the company of all different levels. Overall a very positive experience. HR was extremely friendly and timely with their communication, and the response time was quick. Everyone I met at the office were very friendly. Beautiful location and office, seemed like people were genuinely friends and enjoyed working together. Questions were all fit based, no technicals. Got an offer within a week. Turned it down since I had a few other offers from different companies, but everything I saw about Analytic was ver positive.

Sent them my CV. Was contacted within one week, and asked to take two online tests, an elementary maths one (grade school level) and a personality test. Subsequently, I was called for a phone interview. The person who called me was aggressive and arrogant to the point of being insulting and never introduced himself. He immediately proceeded to angrily tell me that I had too long a CV and asked why I want to switch from an academic career. I explained my reasons, not least that I desire a higher salary, and explained that the length of my CV is due to my numerous accomplishments. He asked me to talk about them, so I listed them succinctly, to which he replied that he "did not understand any of these things and they all went right above his head" and asked me to explain to him what these bring in terms of experience. After making him a list of the subjects and tools of which I am an expert, he told me that I "need to change my opinion of my worth because I have no experience whatsoever". I made him notice that I have almost 20 years of experience in solving hard mathematical problems, and have had actual recognition for my results that have cracked problems that had seen no progress in decades and he actually laughed at me, replying that academic research is not considered valid experience in private industries unless it is about probability and statistics. Finally, he told me that normally they ask the candidates some quantitative questions, but he wouldn't ask me any because "he didn't see the point in it". Frankly, I found this so-called interview entirely outrageous. I felt actually surprised and shocked by this attitude, and I hope Analytic Partners do not treat their clients the same way, because that would be highly troubling. I think a candidate should be met with respect, not with arrogance, condescension and ridicule. I don't know whether I will be invited to the next interview stage, or whether I will get an offer, but given these premises, I doubt I will want to work in a company that hires people like the gentleman I talked to, and if I get an offer I will most probably decline.
