I've submitted the registration form. What's the next step?
Your registration will be reviewed by a member of our team soon. As Hack&Roll receives many applications every year, we are unfortunately unable to accept all sign-ups. We will review all applications and notify you by email of the outcome of your registration.

After registering, where do I indicate my team and teammates?
After your acceptance is confirmed, you may form teams on this website.

What happens if I have already formed a team, but some of my teammates do not get accepted into Hack&Roll with me?
Unfortunately, we may not accept all members of your intended team. In that case, we hope you will still attend the event with other teammates.

I am registering alone / do not have a full team. How do I look for teammates?
After your acceptance is confirmed, you will be added to the Hack&Roll 2021 Discord server, where you can meet other participants and form teams before the event. If necessary, we will also help you to find teammates.

I am an international participant. Can I participate in Hack&Roll 2021?
Unfortunately, our event logistics set-up for this iteration of Hack&Roll is focused only on participants in Singapore (delivery of swag, prizes, etc.). As such, we will not be accepting any participants that do not reside in Singapore. International students currently residing overseas, and are currently studying in a Singapore educational institution, with a valid Singapore shipping address, will be eligible to participate.

I am a participant who has certain ailments or disabilities that will require certain additional accomodations or arrangements. Can I still join the hackathon?
Of course! Please do indicate in the registration form that you will require additional accomodations, and a member of our team will reach out to you, to discuss with you on how we can ensure your needs are well taken care of.

Still have other questions? Please feel free to contact us at coreteam@nushackers.org!
