Bombardier Fullstack Software Developer interview questions

I applied to Bombardier through their website and the HR representative reached out to me about the position asking about my availabilities to schedule an interview. After I provided my availabilities for the interview they just never replied to me. I sent two follow up emails to try and schedule an interview with still no response. On their job portal it shows that I am currently interviewing for the role, however I am not able to get in contact with the HR representative to set up an interview.
