Getting hired can seem very random.

I remember interviewing for a position and the interviewer harped on the fact that I didn't know a piece of software that was specific to their organization. She could not wrap her head around the fact that I knew, and had learned, 20 other programs, including some similar to what she was going on about. I mentally wished her good luck re-hiring a former employee.

I've seen an awful lot of people get hired because they knew someone. In those cases, their lack of skills was immaterial.

Places of business still discriminate: against African Americans, Asians, young people, women, foreign-born … the list goes on and on. Just because it is illegal doesn't mean it isn't rampant. If you fall into a group that is discriminated against you will want to pay particular attention to companies who seem to hire the most people in your group. But still try at other companies!

Keep trying and try to network as best you can.

I have also gotten permanent work through an initially-temporary job. Many retail places hire seasonal employees. This will give you some experience, and for every person you impress at a temporary job, a good reference or networking contact.

Whenever anyone emails me for job openings, I always take the time to reply and I keep their emails, in case I do have openings. Further I try to help them by telling them about potential openings elsewhere in our organization. If and when you are ever in a position to do this -- please take the time to do it. That kind of consideration gives people an emotional boost to keep trying.

You sound like a good hire to me!
