I have to admit to Googling the meaning of "Locus of Control", and I liked what I found....."the extent to which individuals believe they can control events affecting them." Too often we blame everything around us. I like the approach below, and too few people are willing to take a degree of responsibility.
Look For Candidates With An Internal Locus Of Control Our next interviewer tip is to look for people who have what we call an internal locus of control. Now what I mean by that is when people deliver answers, they'll do it one of two ways. They'll either show an external locus of control, which means that they blame previous failures or learnings on their boss or the economy or on the company, or they show an internal locus of control, which means that they own their part in their career journey to date. Look for people who take accountability and look for people who are able to be humble enough to learn from the things that have gone wrong as opposed to assign blame to them.
