I applied my knowledge and experience from another posision i held to the position i was applying for. At the end of the interview the lady asked me if i'd like some water to go and i said yes please. She gave me a styrofoam cup with water in it, inconvenient to take with me. A guy stopped me on the way out and told me not to drink it because it was tap water. He went into the employee kitchen and got me a bottle of water instead. They told me they wanted to move to the next step after someone returned to the office. I followed up two days after that date and they said they were waiting on someone else on the first phase. A week later i recieved an internal email that they decided to go with another candidate and not even go forward with my second interview.
