#4:. The employer whose company has no market advantage
If you find yourself in a company where they have no market edge, you may soon find yourself out of job.
You need some level of job security, therefore you need to know how well a company is doing in the marketplace before you join them.
Do you research on the company, find out what market share they control and how well they are accepted to the buying public.
Applying to this company and being invited for interview, have you heard about them before? Does their name ring any bell? Do they have an appreciable market followership?
