I have been working at RAND full-time (More than 5 years)
At RAND you are working with a select group of professionals, many are recognized as national experts in their field. If you are a military person this is very similar to being in a "selectively manned unit".
Each of us are responsible for finding and maintaining coverage throughout the year. This can be very stressful to new employees or very senior ones as they become more expensive.
Advice to Management
For new employees: Don't hire them unless you have an internal commitment to cover the new employee for the first year.
For senior employees: Maintain contact with them and help them with their career decisions.
I applied online. The process took 4 weeks. I interviewed at RAND (Washington, DC) in October 2017.
The interview process was efficient and organized. I applied online to a PhD level researcher position. Within four weeks of submitting my online application, I had a 45 minute phone interview with a researcher in DC. The interviewer was a senior member of RAND who worked on research areas that were similar to mine. He was very polite and professional. Note: I do not know the outcome of the interview yet because more steps will be required (i.e., fly out with full day interview, if offered to do so) to know their final decision.
