I recently became a little active on Quora. I came across a question there that caught my attention.
“As a decision-maker, when did you hire an introvert over an extrovert? Did you find them more productive or less?”
I think it depends on the role you are hiring for. I have seen that when hiring for an individual contributor role, I might be okay to select introverts. I might even consider introverts for roles like testing, editing, proof reading etc.
I am more likely to select an extrovert for leadership roles, sales roles and roles that require a huge amount of teamwork.
