I applied through an employee referral. The process took 3 weeks. I interviewed at RTX (McKinney, TX) in Apr 2013
Interview
Lengthy and thorough. Did not have to many complex questions but was very detailed oriented to the type of familiarity with the company not necessarily the position being applied for. So seemed a little unusual but after further thoughts made a lot of sense on their needs for employees to understand broader capacities of organization.
