Nice formal interview. The interviewer went over company business model, what do they do and staffs do, training procedure, and career advancement. I feel like I can grow with company. They did offer me the salary for tier 1 support position, but it just too low for my expectation. They offered me $30k salary. I tried to ask a little bit high $35k but they couldn't do it.
