Databricks Software Engineer(Internship) interview questions

I applied online and received an email about the oa after 5 days. The oa should be completed in 2 weeks and it is on codesignal. There are 4 coding questions and should be done in 70 minutes. The questions are medium and hard level, and I didn't finish all of them.

I got link to test consisting of 4 problems and 70 minutes. I solved all four of them in less then 60 minutes and got perfect score. Haven't heard anything from them for more then 4 weeks, today I got rejection mail. Not sure why have they sent me test at first place, but it is what it is.
