In this case, the chicken is the current job from the vantage point of which you see similar jobs to your own that also require a specific skill in addition to what you already know

The egg would be the effort you expend on that skill to meet the basic requirements of the interview for such jobs

The new chicken borne out of this would be you learning on the job and carrying on from the fundamentals you've learned to get the job
