The best thing about career one is that it allows you to post your own resume online. It's user friendly, easy to navigate and has a lot of features to choose from. I have enjoyed using career one thus far. Nothing in particular i dislike at this time. I would say the UI could use some work but it's not very bad. There are a ton of features and filters to help narrow down your search so you can find what you're looking for more quickly. I like that it allows me to be able to see my stats with how many people viewed my profile. This helps me know which resumes are getting the most attention and helps me make changes if needed.
