"Companies count on managers to make smart team decisions and oversee group members in order to maintain deadlines and keep operations running smoothly. Be prepared to answer several situational questions that will evaluate your time management skills, problem solving abilities, and ease in leading a team. Employers will also expect you to be well-versed in products and operations, so make sure to brush up on the department's relevant work."
how did you handle people who don't co-operate?
make them owners so that they will be accountable
explain why, communicate the bigger picture of what you're asking them to do, show that what you are doing is in full view of process/not a personal thing but a strategic or tactical problem-solving approach. If thats not effective, contact his/her resource manager/boss and ask to be added to the employee's review process. Then let his/her boss tell that person you hold this power...
