Codechef not showing participation in long challenge

I participated in long challenge for the first time on codechef. I solved two questions but in my profile it is showing that no participation in long challenge. Why it is so?

I just started coding on codechef and don’t know much about rating system. How my participation will affect my rating? Do I always have a chance that my rating will increase or it will depend on my ranks in contests?

Read about rating procedures here. https://www.codechef.com/ratings

No, it will depend on rank and how others are performing. Check the link.

Wait for some time to get rating updated. probably within 1-2 hour.
