TYLin Many Structural Engineer Positions interview questions

The interview consisted of questions on my background. They discussed the positions they had at several of their offices. The recruiters requested another interview. I attempted to schedule the interview several times. They were very unprofessional in their response to me. The firm prides itself on interviewing candidates for fake jobs so their recruiters can be gainfully employed. One of their recruiters scowled at me and told me to get out of structural engineering. I contacted the head of the firm and received no response. They are very unethical and very unprofessional to me. I was on hold for 30 minutes and received NO response from their corporate office. I can only imagine how the office is like - which I think is very bad. Avoid this firm like the plague.
