I applied online. I interviewed at BAE Systems (Guildford, England)
Interview
Apply on the website by basically just sending your cv. Got an interview invitation very soon afterwards. The interview was 1 on 1, lasted for an hour. About 20 minutes discussing cv, relevant work from my degree and the rest answering two questions. One basic monte carlo simulation question and one on absorbtion/emission of light from a material. The job was almost entirely programming, which I didn't realie.
Interview questions [1]
Question 1
The questions were not difficult, go through a basic monte carlo simulation for the area of a circle, and estimate how much energy would be emitted and absorbed from a box in sunlight.
