What do you think of your previous boss?
Bad answer: “He was completely incompetent, and a nightmare to work with, which is why I’ve moved on”
Remember: if you get the job, the person interviewing you will some day be your previous boss. The last thing they want is to hire someone who they know is going to badmouth them some day. Instead of trashing your former employer, stay positive, and focus on what you learned from him (no matter how awful he really was).
Good answer: “My last boss taught me the importance of time management – he didn’t pull any punches, and was extremely deadline-driven. His no-nonsense attitude pushed me to work harder, and to meet deadlines I never even thought were possible.”
