Got a call from Dyson HR asking me to come for an interview, gave a weeks notice so plenty of time to prepare. Unfortunately HR didn't show up for my actual interview so it was just me and the senior engineer (in charge of floor care compliance) interviewing me... I had applied for a manager role, but was told on arrival that it was just an engineer role (but would be managing a product line). The interviewer wanted to keep the interview short because he needed to take his dog to the vets. I was asked one 'simple' technical question which can be done without a calculator or so I was told... It was not a simple question, the interviewer just didn't understand it and thought the answer was something that was completely wrong. I contacted HR to follow up and they said they would call me the following week... Well I got no follow up call. Overall the worst interview I have ever had!
