But once the contest starts, their submission will be counted to the team they belong. To create a team, one of the user (who is also the team head) has to go to www.hackerrank.com/settings and click on Teams in the left side bar. Then, click on create team. Create a new team and invite members. Ask the other members to confirm by going to www.hackerrank.com/settings. That's all! Once the contest starts, you can submit code from any one of the account and it will be counted as a team submission.
