I would venture to guess the reason why you don't know how to fill in this part of the CV is that you don't actually have these skills yet at any high level. Certainly the wording of the question tends to support this in terms of communication skills. It is too informal and patronizing to women and old people (BTW, I am both).
At a junior level, this is the type of thing I would expect to see:
- A discussion of how well you work with others and how you participate in meetings
- If you have made a suggestion that you had to sell to your team to
get implemented, it would go here
- Examples of your ability to produce written documents, particularly any larger than an email
- If you know a language other than your native language, an estimate
of your skill level such as "Speaks and writes English proficiently"
- Something pertaining to your ability to meet deadlines
- If you have had overall charge of any part of a project, how you
assigned work to others (if applicable) or how you prioritized the
work you had to do based on the critical path.
- You could also talk about how you structured the source control to
make it easier to maintain, or even how you designed code for
Finally if you are very recently out of school, you could put some examples from your schooling. You could also put some examples from charitable work or outside organizations if you have any. I understand that is more commonly put in a CV in Europe. But the strong preference would be to put work-related examples first.
From the perspective of what the employer is looking for he/she wants to know if you can work well within your team, if you can work well with users/clients, if he/she can assign you to write a document such as a technical design, if you can organize your work on your own or if you need to be given the work piece by piece.
If you are at the level where you want to move from junior to intermediate or intermediate to senior, he wants evidence that you are starting to understand the job as someone of the higher level. So I would expect much more of this for a senior job where much more of your work involves soft skills than in a junior job.
As with anything though, what exactly is expected depends on the job. My job requires extensive contact not only with our client, but with the customers of our client. A junior person would not be allowed to directly contact either. So the expectation of the skill level could be different even at the same employer for different jobs.
A government contract might require the ability to produce written documentation while it might not be as important in a start-up. The larger, more bureaucratic organization might require less ability to self-manage the flow of your work than a start-up where everyone wears multiple hats.
Understand that technical skills are necessary, but these soft skills become more important the more experienced you are. I might not expect a junior level person to have much of this, but I would never consider hiring a senior who did not. You need to go out of your way to learn these skills even if it makes you uncomfortable to do so.
