The company gave me a very difficult HackerRank that had a time cap of 1 week. Most applicants had the full week to complete it; however, I was sent the challenge on Wednesday and told I had to complete it by Friday for interviews on campus on Monday, with no extensions granted. I passed the majority of the HackerRank tests; however, I did not have time to fully complete them all. This time restriction was not fair. I got an email the next day (Saturday) saying I was rejected. Clearly, they had not "fully reviewed" my application.
