Sabre User Experience Design interview questions

Applied online and received a email about setting up an interview and a front end development challenge which was about 7 coding question. This was not part of the job requirement or description so wasn't sure why i was asked to do it. But i completed it to the best of my ability.They said to contact them if i had questions so I emailed them asking about the programing and didn't hear any back. I followed up after a few weeks and still didn't hear anything.
