Initially the interview was solid and the hiring manager was friendly and outgoing. Met with some other SEs as the process progressed. Final interview was a PPT presentation based on a pdf shared with me. I spent hours building the ppt and making it clean. The hiring manager wasn’t happy during the group interview, his tone changed completely and the rest of the team followed his lead. Condescending and belittling tone come to mind. He expected me to describe in detail how to implement their product with me not knowing anything about their implementation process. They told me I should have just made it up. Truly a horrible experience and I will never talk to these folks again.
