Barclays Scrum Master interview questions

Terrible Process and horrible HR. After submission, a Lead Corporate Recruiter at Barclays Greater Philadelphia Area reached out to me by email asking my expected salary to be eligible for consideration. I replied to the mail with expected salary and he came back asking my Resume (again !!), I had already submitted the Resume with application. He also informed that Barclay's was conducting interviews on 2 days (Wed 2/26/19, Thurs 2/27/19) at Whippany NJ office. I asked to get the details and specifics of the interview but he never bothered to reply or call. He provided a wide 4 hr. range on a work day and no name of interviewers, neither any other specifics. I believe it was a crazy WALK-IN and he was blindly reaching out to candidates. I didn't even think to attend such an unorganized walk-in without any prior technical/HR discussion. How do such people call someone in-person without any prior discussions. Just wastage of people's time. Do people go for such unorganized walk-in's at 15 plus years of industry experience or this guy was just bombarding the inboxes to see few might turn out. Is this what Barclays is? Terrible interview process... Never faced such a HR in my lifetime. Horrible experience.
