Filtec Machine Vision Engineer interview questions

I applied on their company website. After a few months, I received an email for a phone interview. The phone interview with the recruiter went well and was told that I will be receiving a second interview. After about 1-2 weeks of not hearing anything back from the company, I sent them an email. I didn't receive a reply so I had to send them another email. I received a reply that they are looking into scheduling the 2nd interview. Nothing happened after.
