The process took 5 weeks. I interviewed at NRG Energy (Houston, TX) in Dec 2010
Interview
I applied online for 2 positions. About 3 weeks later HR calls and says she loves my resume. She ask me a few questions about my pay, vacation, bonus etc. She wanted me to meet with both hiring managers (so she said). One was out on vacation. She said she would find a day when they both were available and schedule an interview. She never did. I received a rejection email about 2 weeks later.
I applied through an employee referral. The process took 4 weeks. I interviewed at NRG Energy (Austin, TX) in Nov 2014
Interview
A series of phone interviews with the corporate recruiter at NRG as well as members of the marketing team. Last round was in-person. It's important to understand that there are many brands that work underneath NRG so in hindsight, it would have been important to ask the strategies and plans for each of the brands and companies that exist underneath NRG.
