St Mobile Aerospace Eng. Inc. interview questions

3 Interviewers conducting interviews. totally not professional. give very brief details on job yet ask me lot of qeustions and insist that i lower 10% of my current salary. did not bother to read up my resume before asking me down for interview. totally disinterest in giving job details after they ask me about myself and they find me unsuitable. totally wasted my time going for the interview. their job ad was so brief with job title only.
