To reply to Govind's question. I got a 15% raise when I passed the CQT in March, and will get another 15% for passing the CQE. No financial benefits though from any other exams that I may choose to take in the future. Those two were requirments since I was hired with very little quality experience.
I've been studying for these exams pretty much non-stop since January, and I'm going to take a well-deserved break.
