alternative to hackerrank

Hi,

Do you have any substitute for www.hackerrank.com?
Actually, I have to prepare for my placements and when I solve the challenges on this website, I am not sure from where to see my progress and mistakes.

Can anyone recommend me a similar site for my placement preparation?

Disclaimer: I am affiliated with www.kattis.com.

You should check out open.kattis.com it is the official tool used during the ICPC world finals in programming. Also used in recruitment by some of the worlds top startups, like Spotify.

Best,
Benjamin
