PPG Modeling Engineer interview questions

They emailed me about 3 months after applying for an interview. I did a 30 minute video call with two team members and they asked a mix of behavioral and technical questions. They never got back to me afterwards but I also never followed up since I didn't want the position. They did say they would follow up within two weeks though and that never happened, not even an automated rejection email. One of them his English wasn't great, which made his questions kind of confusing, so I had to clarify a few times before being able to answer.
