We hope that candidates who join can give their all during working hours to promote the growth and progress of the company together. If you are highly committed to work and teamwork, and are willing to use your creativity and abilities in your work, we very much welcome you to apply to join our team! --- This way of expression not only clarifies the expectations for work attitude, but also maintains a positive and respectful tone. I hope this helps you!
