I believe it really depends on the situation. When you are looking for a job, I think that IQ is definitely more important because you have to show your skills and knowledge. But once you've landed the job, everyone around you will have more or less the same IQ level as you. So this is where EQ comes into the picture. Not all people in your workplace will have the same EQ which means that it can have a significant effect on your success within your company, and afterwards, in life.
