I liked almost everything about the platform. It has great tutorials, focused test problems that test aspects of your programming knowledge and helps you build your skills one piece at a time and it never felt overwhelming. HackerRank also has a great community of people who will help you out if you ever get stuck somewhere. It also has a leader board, which helps you track your progress with respect to other programmers and feels very rewarding. And all of your hard work can be seen by people looking to hire someone. You can also get certified by giving small 1.5 hour test which should be a breeze if you know what you're doing and all of this is for free, the only investment that you need to make is with your time and not your wallet.

Only the fact that there need to be more certifications. I feel that there can be more fields to certify in and it may be implemented in the future. Review collected by and hosted on G2.com.
