SmartAction Software Engineer interview questions

The first round was a phone interview with one of their software engineering directors. I didn’t know it was going to be a technical interview, but the second half dove into a bunch of technical questions. I did get called for an onsite interview afterward. I emailed the coordinator asking if they offered reimbursement for travel to the interview. She said she would email back with information and never did. I sent a follow up email to no response. It’s extremely unprofessional for a company to ghost their candidate randomly for asking a question about travel reimbursement.
