This is the rudest interview I have ever gotten. The HR person contacted me after I applied through LinkedIn, asking me to have a phone interview with her by giving her my availability on an online calendar. HOWEVER, she never confirmed the time with me and just randomly called me in the following week. RED FLAG! The HR person basically has no respect to the interviewee and doesn't respect interviewee's time at all. You cannot just call people without scheduling a time and randomly call them. Not everyone is in a convenient situation and sits there waiting for your call.
