Jacobs interview questions

A recruiter reached out to me on the phone. The recruiter left a message, however, I could not understand a single word she said in the message so I returned her call. I had a technical interview over the phone with 2 engineers. They said it went great and would like to have me come in for another round of interviews. I never heard back from the company. I reached out to the two recruiters I had been working with form Jacobs and they never responded to my emails. Very unprofessional. I certainly have no intention of ever working for Jacobs and will also tell my experience to others in the field so they too do not waste time interviewing with this company.
