Ericsson Technical Support Engineer interview questions

I applied online after noticing an online advertisement for the position. The HR rep contacted me within a few days for a brief interview over the phone. He then stated he would have an HR coordinator contact me to arrange an in-person interview. The coordinator contacted and asked for my availability and proposed a few dates. I agreed to all dates proposed and stated I would be happy to accommodate with regard to the time of day. However, the in-person meeting has yet to be confirmed all the dates have passed. I was told the people conducting the interviews have a "full schedule" and I will be notified when they become available.
