I see things like that and assume that everyone involved in writing, reviewing, and processing the position it advertises is either incompetent, negligent, or playing a game. Ultimately, I don’t care to know why, because there are other jobs with better teams at better companies.
If I took the time to ask probing questions every time someone makes a bad first impression, I wouldn’t have time to work, eat, or sleep. My heuristics have served me well, and I’m sticking with them.
