Tech recruiter here. Firms on average are more dishonest than jobseekers. The reason is simple: If you do something often enough, you get sloppy.

For instance, if you start going to the gym, at first, your exercise execution is perfect but after some weeks you get sloppier and sloppier.

Same here, firms that are hiring constantly tend to get fatigued. Jobseekers, however, are "active" for some weeks until they switch jobs; this is why you, as a jobseeker, need extra training during your jobhunt, to be on-par with them.

I don't recommend lying but I do recommend tailoring your resume such that it reflects actually what you did in an adequate level of detail. Most job seekers are too honest on the CV and during interviews.
