Grant Thornton interview questions

Would like to say I got an interview at Grant Thornton but I didn't. I received a message from Grant Thornton HR asking if I was still interested in the position I had applied for 2 months prior. I called back multiple times and sent emails with no response. I then received an email from Grant Thornton Recruiting saying that my resume was no longer being looked at. Highly unprofessional to call someone and never return a call back. I was even referred to the position by another Grant Thornton employee.
