IXL Learning Software Developer New Grad interview questions

Applied online and got a link to a hackerrank challenge the same day. The questions were easy and I passed all the test cases with time to spare. However, I got a generic rejection email shortly after. Honestly feels like they didn't even look at my resume until after the coding challenge and instead wasted my time.

Was sent a 90 minute Hackerrank coding challenge that was to be completed in 3 days. Completed the challenge with all test cases passed and lots of time remaining and was sent a generic rejection letter the following day.
