I applied online. The process took 2 months. I interviewed at ALSTOM (London, England)
Interview
Application Form, Skype interview, Group assessment, Individual interview
The initial application, interview and assessment centre were all very positive. Everyone I met was professional and friendly, and I came away thinking I would very much like to work for this company.
However after this it seemed many errors made by recruitment, for example, wouldn't say salary, long delay in getting actual offer. Odd mix up where I was being invited to 3rd interview and informed I was starting the following week but had no offer or knowledge of location in London. Sadly this put me off as despite the people I met who were good and the description of the job and scheme appearing interesting, I took this as a red flag.
