The owner/CEO has and cultivates something of a cult of personality. Everyone spends significant effort trying to please him (and I'm not sure many people realize it). This is partly a result of RTS's recruitment, interview and retention practices. You should know that this cult of personality exists. If you are comfortable "sucking up" and either appearing busy or avoiding the appearance of any problems, at least from the CEO's perspective, you'll be okay; suck up extra if you want to get ahead. Otherwise, just avoid this place. If you anger the CEO, prepare for a very brutal and public excoriation without warning.
The project management methodologies are also pretty lousy. Not the worst I've seen in the industry, but fairly poor. The main project manager (at least when I was there a while ago) seems to be more concerned with making Costco trips, erecting Christmas trees and planning office parties rather than being an effective PM. You may be assigned to a project for which you don't have the requisite skills or expertise, and you will be blamed for the resulting failure.
Inefficiency is something of a problem. The office is organized as one giant open space, with Ikea tables set up as desks. This is fairly common in the industry, and is bad. RTS was foolish to emulate it. The time entry system is also awful. RTS uses a system called TeamWork, which has multiple bugs and just a user-hostile user interface. Prepare to spend a lot of time being frustrated at this software. (RTS originally used Harvest for time entry, but couldn't justify the modest cost and so shifted to TeamWork.)
Most of the people are quite good, but there are a few key curmudgeons who more or less reject any ideas they haven't thought of. Since the company has a cult of personality, this is fairly problematic. Prepare to appease them along with the CEO.
Finally, this place has a *massively* overinflated estimate of its importance. As it grows, RTS is becoming more of a run-of-the-mill Java consulting shop (with some .NET thrown in just for fun!), but to hear the owner describe it, they're an innovative, cutting-edge company. The owner appears to believe in his own propaganda
Overall, it's a pretty lousy place. It's really not the worst place I've worked, but it could be a lot better. Once you dig below the surface, you'll find that working to make a relatively impulsive and emotional person happy is not fulfilling.
