Vantaggi
Some really smart people doing really good work for customers. Front line employees always willing to share knowledge and go the extra mile for customers and others within the organization.
Svantaggi
It took several years but the acquisition by IBM has ruined what Red Hat once was. Unrealistic targets based on incessant need for growth rather than based on real world numbers or data. Red Hat never even broached the subject of a resource action prior to the IBM acquisition and now those left need to get used to the IBM approach of at least two RA's per year. This place is a pressure cooker ready to explode due to quarter to quarter unrealistic targets. Senior management is feeling the enormous pressure and have been flailing about for the last year. Their only response has been to push the pressure down to the people doing the real work and if that doesn't work start letting people go. There now are much better places to work where your contributions will be more valued.
