I had three interviews. Two phone interviews and one in Malmesbury a village in UK.
The first interview was general questioning mostly about the CV.
The second one was more formal questions and the third one was basically getting very much information from the candidates regarding to sound isolation and noise and vibration path analysis.
Be aware to not be open that much and just give information. They even give a vacuum cleaner and just get all the information you have regarding to solving different problems in noise and vibration aspects.
They also expect specialist work for them cheaply.
If you want to get a good position in Dyson you need to accept these two hints:
1- You should not expect to get high salary based on your knowledge and competences
2- You need to be humble and give them credit
In general, I got a very negative feedback from the company both from the location and their policy. They supposed to return back 450 pound to me which indeed they have paid less as I did not kept taxi cost from Bristol to there ( which in two ways it cost me 130 GBP).
