US Tech Solutions IT Recruiter interview questions

HR person was initially till the time i gave interview, was responding to my email and calls. After the interview, HR person didn't get back to me, so I drafted an email to follow up but HR person didn't dare to response. It is the liability of HR to give response to candidates either result is positive or negative..

Just received a call from a recruiter looking for an IT recruiter. She was more interested in getting the last 4 of my social security number and my date of birth. Wjy do you need this info in a first conversation. This feels like a scam! If you are a legitimate company looking for quality candidates do not ask for this info on the phone, especially during the first conversation. After I wouldn't give her my very personal and confidential info she hung up on me. This is not how you conduct business.
