My team works for a company in another country(Some hours of difference) and we work together we that company's team to develop their product. In the last couple of weeks I've been working with a senior developer of that company that everybody on my team said was a pain in the ass to working with. I didn't want to judge the guy just by others experiences, but man they were right. We're talking about a guy that has years of experience. However he is incapable of retaining any kind of simple business logic or process and leaves incomplete code everywhere (not tested properly and buggy). With the diference in hours, every morning I when I look at the hand off messages and there are multiple questions that he should know better than me(has more time in the project than me) and a lot of code that I have to fix! This guy can't complete simple tasks that could be almost copied and pasted from other parts of code. What gets me even more pissed off is that this guy has a better salary than any person in my team and does a lot less and with poorer quality. And to top it off his company management doesn't acknowledge that he is a problem...
