Tell me about a time you made a mistake."
The best answer for this question involves learning something from a mistake. If you are having difficulty thinking about a mistake you made that will be an effective answer, try to think of a lesson you learned that improved a good trait. Making a mistake is not good, but since you have to tell them something, you should tell them something that makes you look good. For an example, let's create a scenario where you learned how to be someone who anticipates problems.
Short Answer
I was given a project to complete in a week. I understood the project, but I misinterpreted one section. After completing the project, I was told by my manager that it was done incorrectly. I really made a mistake by assuming incorrectly in one of the sections instead of asking for clarification. I learned not to assume through the mistake I made.
I had a project I was working on, and while I was in the middle of typing up my documentation, my computer started acting weird. It froze for a while and so I rebooted. After 10 minutes, the computer showed a blue screen saying that there were problems and recommended that I reboot the computer again. After another reboot, everything appeared to be ok. I continued my work and finished for the day. I spent two days on this assignment and when I went to retrieve my data the next day to double check my work, my computer wouldn't start up. A technician came and found that my hard drive malfunctioned. I lost all the data and lost two days of work. I was disappointed and thought I would never trust a computer again, but there was a great lesson to be learned. I had a couple of warnings and I ignored them. From then on, I practiced being someone who can anticipate problems. I now think of potential problems ahead of time and pay attention to details along the way. If I applied this sooner, I would have saved the data on another computer and I wouldn't have lost a couple days of work. But I can't say I regret making the mistake because it made me someone who can anticipate problems better.
