Dyson Process Engineer interview questions

Telephone interview with Dyson recruitment. Telephone interview with technical manager. Face to face interview with technical manager at malmesbury. Follow up telephone interview with senior engineer. The process was quite drawn out due to scheduling difficulties but not unnecessarily so. The interview itself was compentancies and behaviours based, included a short presentation and offered a fair opportunity for me to showcase applicability for the role . All stages seemed to go very positively but no offer was made. I was disappointed not to be contacted to be told the result. A phone message and email requesting confirmation of the outcome were both ignored. I would now be reluctant to apply for roles with Dyson in future.
