'I had such high hopes for this company, but now I just feel disgusted': Job candidate left stunned after business manager spends 95% of the interview bad-mouthing his coworkers and colleagues

What would you have done to get yourself out of this nightmare interview as soon as possible?

This job candidate thought he had found the perfect company. The position was well within his skill set. The salary was decent. The benefits were exactly what he was hoping for in his next role. Even HR seemed excited about his potential at the organization. 

There were seemingly no red flags…. until he met the business manager who would be leading his team. Pretty soon into the meeting, it became clear exactly why he had such trouble maintaining loyalty among the folks who worked for him.
