Mercury rolls out tools like Confluence with absolutely ZERO training. You're expected to use the tools to help management micro-manage every aspect of your work. This creates even more work for you as an employee that does not make you more efficient. Much the opposite, it slows you down as you have to do things multiple times and report progress using multiple different tools.
There is absolutely no correlation between performance and pay. Work really hard? Work long hours? Work more efficiently than others? Congratulations on your 3% merit increase while your lazy coworker who contributes nothing but sucks up to management very well also gets 3%.
Mercury is a company that gets things done through a series of diving catches. If you participate in a diving catch, you are rewarded. If you plan ahead and prevent a diving catch from being needed in the first place - expect to get criticized/scrutinized. Mercury rewards diving catches and a lack of planning.
