I can testify to this. I became sound in the use of Html & Css in just about a month. My CCNA skill is also sharper than ever. Learning takes effort so i know i would have to do more research and reading to be very good. Check All-tech out.

I think people get these fake job interview messages after applying for jobs on job sites like Jobberman. They are not that reliable afterall. I've gotten several messages from these people without actually applying.
