An interview

Last month I decided to quit to DHL. After being there for a couple of months, I felt I wasn't challenged enough at by the job because there wasn't room for advancement in the company. but (however) I really enjoyed working there and appreciate the skills I developed while with the company. I'm now planning to apply for a lot of jobs to go on working in the IT field. I will see what happens. I've been unemployed for 1 month and what I want now is just to get some job offers. A friend told me there are companies taking on five hundred engineers for a full-time job. My priority is to get a job offer or first get certified in Cisco so I could cast a wider net when going job hunting. And, I think that's the best idea thing to do now/best idea for now. I also have to decide whether to work in the public sector or private sector, as I've applied for jobs in both. I got some sound advice from my mother telling (advice telling or mother telling?) me that I could work for a company because that's where the money is. Anyway, I'm ready, I have my resume, the address of the office where I'm going to apply for and my transcript. I think I need to be respectful but not meek. I want to be professional with everyone, my co-workers and my bosses. But, I don't want them (whom?) to think that I would let my co-workers walk all over me. I'm confident, I won't make the mistake of making things up. I know I do that sometimes when I get really nervous, you know, my brain stops working and my mouth takes over.
