The process has recently changed. My interview at GA was very thorough and well put together back when hiring managers had more say in the process. I got to meet the team, had to give a presentation, got a solid tour, and was given very difficult questions. Now the managers must have an HR representative there at all times, team members don't get to meet the interviewees, no lunch with team members, and the presentations only get a few select managers rather than the team you'll be working with. Really they have made the hiring process less selective and it shows in the level of competence that has been degrading over the last few years.
