I was interviewed by two ladies who, though pleasant and courteous, seemed like they had already been through several interviews that day and were tired. The interview was like a game show speed round, with the interviewers taking turns asking a succession of rapid-fire questions. There were no outrageous or "tricky" questions, other than the famous "how do you make a hamburger" question. I believe they are looking for a detail-oriented answer there. I believe the interview took no longer than 15 minutes.
At the end of the interview, they said that they had a few more interviews to get through, and that they would contact me with a "yes" or "no" by the following week. I never did receive any contact from either of the interviewers, nor did they return my phone call inquiring as to their decision.
I was disappointed to have not received any communication after the interview, but as this was for an entry-level position, I suspect they made a determination as to who they would be hiring and simply did not see the need to follow up with all the other interviewees.
