Pros
The best reason to work at Deltek is the flexibility. You can work from home and they're great about letting you have time off when you need it.
Cons
The downside of that is that most of the development and QC is in Makati (12 hours difference) and you're expected to have meetings on their time, not US time. So there are a lot of night meetings. Another negative is that management has quarterly layoffs of anyone with product knowledge or anyone who disagrees with them. The result is that everyone is doing two at least two jobs and completely demoralized. If you're a QC manager or a project manager, stay away!!! Those two departments have extremely high turnover. Pretty much everyone in Engineering is just waiting for their turn to be laid off as soon as their knowledge is transferred to Makati.
