When I write that they are relatively plentiful, it means in comparison to other entry level jobs in the industry.
QA jobs are not frequently advertised, and they fill up fast.
Some companies staff up in a big push once per project. In that model you have 20 or 30 openings all at once with a very tight hiring window, perhaps just a single week out of the year. Other companies have a continuous flow of QA folks, mostly hired by word-of-mouth.
This is in comparison to other fields that may only have a handful (0-5) of entry level positions open every year.
Ok. So the best job strategy would be to just go to local employers and ask about vacancies or via networking.
