NetSuite Technical Analyst interview questions

Applied online and hear back about 2 days later asking to set up a brief 15 minute informational sort of interview. Was basically a background on me and background on the role. Next a more formal 30 minute video interview was scheduled with one of the hiring managers. This interview was also very straight forward and I was asked no technical questions. Next was a super day in Chicago. this consisted of a evening cocktail hour to schmooze with the interviewers and then a full day of interviews. Sections were a group case study, a few informational sort of overviews 2 individual interviews. All was done in the conference room of the Hotel, literally everyone was slugging coffee trying not to get tired. Ended up getting the offer which was bizarre. Recruiter called to let me know I got it, asked me if i wanted it. I replied that i would need sometime to decide. He gave me two days but said he wouldn't give me a formal offer (aka anything on paper) unless i agreed to sign it. The recruiter wasn't clear on the deadlines and after asking for an extension was basically ignored by the recruiter and a few weeks later sent an email declining the offer.
