My guess is that he's taking issue with this argument that I'm not quite sure was made:

"The market is flooded with people who cannot code, therefore it's easy to find a job as a junior engineer"

The market could in fact be flooded with people who cannot code (I don't know for sure). Assuming that's true, that doesn't necessarily mean it's easy to get a job as a junior dev (speaking from someone on the interviewing side).
