Comcast Web Developer interview questions

I reach by 11:30 and the waiting time took around 30+ minutes after that the interviews was happened through Phone. They asked all the basic questions and I felt very happy after I done my interview and here the twist comes 😒 with in a 2 minutes they asked me to leave bcz my profile is not suitable for their position, What ? When I asked for a reason they don't have any answer for that, Seriously! At least they should give me a proper response so that I could convince my self but right now I felt like that I put into the black box 😒.
