Appian Software Engineer - Full Stack interview questions

A recruiter approached in LinkedIn. I asked if the role offer sponsorship & only after recruiter confirmed they can. I accepted for recruiter call. Recruiter call : - Intro about the company, team , JD , stack of technologies - Intro about myself , work experience & stack of technologies I worked on - Difference between my current & previous work experience - What is the proudest moment in my current job ? - What do I enjoy working on Front end or back end stack ? - Why am I looking to move ? - Work authorizations ? - Daily duties ? - What type of methodologies followed in current job ? The call was around 45mins & he said he is pretty impressed with my experience as I explained & also gave me insights of 2 positions I would be fit for & he would reach out to the managers & share my profile. Recruiter mentioned there is sponsorship for sure & said he would send out next steps process after discussing my profile. I waited for next round of interview steps for 5 days & followed up with recruiter. Recruiter got back saying they are unable to move forward due to visa sponsorship. I felt very bizarre, why would they even call me at first when they are not sure of sponsorship details of the position when I clearly asked for it in the first place. I just suggest the recruiters to not waste a candidate's time without giving correct information before even starting the process.
