I worked at Prime Technology Group full-time (More than 3 years)
At Prime you will typically be working with the latest technologies as their focus is on project based work not maintenance assignments. Overtime demands are the exception.
Their business model is to have a Project Leader onsite in the US and the team of developers and QA based in Hyderabad India. This makes perfect sense for clients looking to leverage the global workforce and reduce their costs. The downside is that there is little personal interaction with your US based colleagues.
Advice to Management
I would have stayed longer than 3 years if there had been a career development program.
I applied through other source. The process took 1 day. I interviewed at Prime Technology Group (King of Prussia, PA).
3 interviewers and one phone screen - pretty easy but they do ask relevant questions regarding the project they want to use you for and give false timelines too.
