I have only been working at North American tech company for 9 months now. And for most of projects I have worked on till now, I have been super fast and finished my work mostly before deadline/estimate. My question is can this fast work backfire on me? My manager has always praised me but can it be bad like me being disliked by team mates or having problems in future? Should I slow down and finish it slowly (In that case, I am not sure what do I update in project syncs if I have been lazying around and not doing much)? Or continuing at speed will be beneficial for me?
