Your video is recorded? Great! Now, a video editing program can give your video the final touch.
Don't worry, you don't need an expensive program: There are several free apps available for mobile phones that allow you to do basic video editing. But don't overdo it with special effects – after all, the application video is primarily to get a personal impression of you.
