I applied online. The process took 3 days. I interviewed at Mars (Slough, Berkshire, South East England, England) in Jan 2018
Interview
long process, combination of online and on site testing, they keep on changing the interview structure I believe due to the very high number of candidates applying for the job. This is due to the job title and the job description is not a clear reflection of what they think they are looking for, or even considering if you have actually worked in the industry before.
Interview questions [1]
Question 1
aptitude testing, they are basically looking for mechanical engineers to run there lines for quick repair.
