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.

So far so good. The technicality of the questions are challenging but as far as you have that experience, it shall be great. Explain it with passion and precisely. Keep mentioning that your passion towards the job that you have applied
