I was approached by Serco to attend an interview, I was given very few details about the actual role, then was never contacted by them following the interview, despite sending a chaser. I found the entire experience somewhat muddled and frustrating. This is not a company that I'd be looking at in the future. The actual interview was fine, but were quite specific to particular areas of knowledge that the HR team had failed to share with me, despite requests.

An easy, straightforward process includes 1 call with a recruiter, 1 hour call with a hiring manager, and 2 short calls with top management. Situational questions and more of a conversational style.
