Bullhorn Software Development Engineer In Test interview questions

HR contacted me upon coming across my profile. I was given screening test link, I cleared it. So far so good, not much info on role etc from HR. After sitting with f2f panel, realised they are looking for something I never worked on. I asked why did they even call me, didn't get proper answer. Looks like HR and whoever filtered my profile were not paying much attention to the details. Beating around the bush simply my time was wasted.
