Alarm.com Internship interview questions

Had a quick HR phone call, then set up an appointment for a 'technical interview' calll. The interview was super easy, just conceptual coding questions, no actual coding was done. Got a follow up e-mail asking for unofficial transcript and to fill out employment application form. Seemed like everything was going well, but I assume once they saw my GPA from the transcript they didn't want to hire me anymore. Considering how easy their technical interview was, if they're going to discriminate based off GPA they should have a requirement straight up before people apply so they don't waste the interviewee's time.
