Sentinel Group Software Engineer interview questions

I was contacted by the recruiter for phone call. conversation : Hi we would talk about your background and I will let you know about the company. But first I would like to know if you require sponsorship. I said yes I would require in the future. Ok then We will not be moving forward with this interview. "If you do not provide sponsorship that is completely fine. But at least mention that thing in the job description. I wasted my one day preparing for the company and understanding everything job and requirements"
