I was recently laid off after three years at CTCI-A. During this time I work on a total of two jobs and then sat around doing busywork for two years. While at in its infancy the architecture team was a great team to be on. During my time at the company the turnover rate was high. The parent company in Taiwan controlled every move each team was making and hindered growth of the teams. Now the USA based teams are acting as quality control specialists to teams based in Taiwan. You definitely feel undervalued as an employee.
