The skills section is a must have for technical people. However, for non-technical people, this can be skipped.
Skills section is an easy read for technology recruiters. A recruiter can easily filter out people who do not have the skillset for the opportunity she is hiring for.
Skills section has the potential to send right signals to the hiring manager. In the world of technology, the hiring manager gets a view of how full stack the candidate is, the software development and deployment process the candidate is exposed to etc.
Skills section should talk about the hard skills and not the soft skills. Obvious hard skills such as MS Office should be skipped. Another point to keep in mind is that laundry lists do not help. Hence all the skills should be put under standard buckets to improve readability
To summarise, the importance of the skills section in a resume depends on your profile and seniority. For technical people, this is critical. However, for non-technical people, this can be skipped.
