Galooli interview questions

a recruitment manager called me one day while i was in the middle of something and I asked them to call me back the next day at 11am-12pm. They said ok, but the next day no one called at all. And a week after that an HR called saying "we spoke last week and we would like to have an interview", it was funny that they somehow thought they spoke to me. The interview itself was okay, but honestly made no sense to me, because it was not with the hiring manager. I did not get the job, but that's good, cause if a company has no structure during hiring process - I cannot expect them to have it later in the process.
