Do you think resume is the best way to judge person's abilities?

Not at all. An interview will give the potential employer a much better picture of the candidate. 

Resume is not the BEST way to judge a person's capability, however it definitely is the very FIRST communication source b/w candidate and employer. And first impression is the last impression, they say. So it goes back to candidate's shoulder how he makes this last impression as lasting. 

So we cannot categorically deny the importance of a resume at all. It does tell quite a bit about the candidate, but should not be the only way to judge the candidate's skillset.

Hiring someone because they have an impressive resume is like buying a car because you love the brochure.

You need to avoid lemons when you’re hiring too. That means treating the resume like an advertisement – good for basic information but not the whole story.

A candidate’s education, skills and experience will be the first things to catch your eye. And, of course, it does matter who the person has worked for, which technologies he/she knows, and how many people they have managed.

But what you’re really looking for in a great hire are the qualities you can’t list on a resume – I call these brains and heart. They’re at the root of a person’s ability to confront unexpected challenges, to demonstrate wisdom and judgment, and to develop into an invaluable part of your team.

Best way or not, this is the only way we are judged for a vacancy. Especially for people looking for an opportunity abroad.

Resume is 'THE first impression" of the candidate. It certainly have a value in the selection process.

But, we cannot argue the need of a Face to Face interaction to make final decision.

There have been many instances where candidates put false information, just to get attention and to get shorlisted..

A person's ability can be evaluated by the interview, and the person's character, personality and skills which they have and they describe which could help the company.  

Being willing to learn, to train and to be adaptable are also qualities a person needs to have.  

A good work ethic and history of punctuality, little sickness record and genuinely wanting the job will also provide a good impression.

your CV show your qualifications and your skills  , but the interview is the way that judge you depends on your personality and your experience that you  show on the interview

For the time being, yes it is!

No , the resume just identify your experience, education and training history ..to good know the person you must work with him to see his ethics and potential and his real skills and competencies !!
