I applied in-person. The process took 4 weeks. I interviewed at bp (Chicago, IL) in Mar 2015
Interview
To determine who would be laid off, the company developed a process that required each group member to prepare a self evaluation, have an evaluation conducted by 3 unknown peers, interview for your current position and be evaluated by your superiors. This was all smoke and mirrors to eliminate 25% of the staff which was heavily weighted with employees over 50 years old.
