Costello Medical Intern interview questions

At first, I was really excited to apply for this role in Costello Medical, and the culture/research they showed on their website is quite appealing. But now I was so disappointed with their discourtesy and lack of professionalism. Throughout the interview, the recruiter showed little interest in me and was obviously absent-minded. I received no response after answering the first question and had to say hello after 10 seconds to check if she was still there, which is ridiculous. Unsurprisingly, I got rejected and received a standard rejection email (highly competitive and regret to inform you) with the outro (please do reach out if you have any further questions), so I sent a follow-up email asking for feedback but received nothing, literally nothing. I spent hours researching their websites, writing a cover letter and preparing for the interview but they won't even spend 5 minutes providing feedback, so ironic.
