Ex-boss (who boasted 20 years of programming exp.) Would not let us work on a web project saying we didn't have enough experience and said he'd do it alone... Fast forward to 3 days before presenting to client, we get to check the log in interface and immediately find that there's no actual security, no validation... Just 2 text boxes with hard coded users and no way to add more without creating them in db... And if you knew the next page's URL you can actually skip the login... Needless to say he was removed from the project that instant and we (interns at the time) had to do everything from scratch. A 3 months project done in 2 days. Never been more stressed in my life :'(
