Nephron Pharmaceuticals interview questions

After applying online, I received an email asking me to schedule a date and time for a phone screening. The conversation went well, and the manager asked if I would like to proceed with another interview with upper management. The following day, I emailed to discuss the next steps for the interview process, but I never heard back from them again.

I got an interest email two days after applying. After making contact I had a favorable video interview. Then I was asked to come in for a tour and on-site interview. The on-site visit went well. I was impressed and shared my interest. I later sent an email thanking the person I was in contact with and interviewing me. I got no response to that email. Nor to the two emails sent after, expressing my continued interest in the position and company.
