The last interview required to present a work sample by analyzing data and share your own negotiation style with vendors. The Power Point will need at least 2-3 days to prepare.
The whole process was very smooth except one of the interviewer was walking on the treadmill the whole time and it really disrupt me from presenting the content.
HR was responsive, followed up on the hiring process, answered the questions. However, I was told after the last interview, the hiring manager likes my presentation a lot and my background fits exactly what they're looking fo, but the position was currently closed and they're not accepting any candidate at the moment. Not sure why they post a job if it doesn't exist.
