"Yes, I am!"

Sales answer example
"Absolutely. I really value a team environment because talking things out, leaning on each other, and working collaboratively are so crucial to anyone's success. I've always enjoyed most when our sales organization is set up with a team atmosphere. That is, in order to succeed, you need your pod or teammate to also succeed. In such a competitive field, you need to put into place some policies to remind everyone that we succeed together and that an individual's successes can only go so far.
I am always happy to help out the team, and have demonstrated this in many roles. On numerous occasions, I've covered for assistants to help set appointments for another team member, or taken over someone's accounts for the day, or even for an entire maternity leave, all while managing my own book of business. It is an additional challenge and fun to put on a different hat, all while helping out the team."
Retail answer example
"I'm definitely a team player- I know full well that the department itself, and the store as a whole, will not run if we are not working as one cohesive, collaborative unit. I am always willing to lend a hand and help out a coworker, from taking an extra turn cleaning out the dressing rooms, to working an undesirable shift so they can go see their daughter's recital, to bringing the schedule home with me so I can tweak it to fit the requests and needs of the department; you name it, I've done it and am happy to do it again."
Marketing answer example
"I would certainly say I'm a team player. I've been in organized sports my entire life, so I know that without a team, you can't accomplish very much. I really value the relationships I have formed from working in teams throughout my life, not to mention how much I have learned from my coworkers when collaborating across departments or across the hierarchy of the organization. All in all, I know the importance of a team and I work very well in a collaborative environment."
