Vericheck interview questions

I applied for this job by recruiter. Was put in touch with the CIO and had a phone screening. Was a fairly technical phone screening which I didn't feel great about. I didn't know a lot of what he was asking. Despite that, was given in person interview which was very technical targeted towards Software Development, which makes sense given the position. Was told by the recruiter I would get an offer despite doing terribly in the interview, but ended up declining because didn't feel it would be a good fit for me.
