Contacted by the HR / Recruitment person within a few days of applying online. A half hour telephone interview with the hiring manager was soon arranged. This was pretty straightforward and was invited for a face-to-face interview at the Atkins Bristol office soon after.
The interview, which lasted about 2 hours, was friendly yet very professional. No really difficult questions. I came away thinking I may have got the job - I didn't. Got the "sorry, not this time" email the very next morning.
