Taking Calls In an Interview

“Heh, can I just take this call I’ll be right back.”

I never got a chance to answer he just took the other call. Waiting patiently for about three minutes thinking should I just end the telephone screen now or be polite. I can overhear him talking to someone saying, “No big deal I’m just doing a phone interview. Yeah we can order some pizza later.” He apparently was talking on his cell and leaving me on pause on the land line.

“OK, sorry about that, I just needed to answer the call.”
