What really matters when an employer select his staff? Professional experience or professional certifications?

obviously professional experience first preference.....but may ask for certifications as per the company rule......

I think it's useful professional experience in work more than a certificate and because of that during the work the employee faces problems, mistakes and difficulties have not learned before through his academic studies of any professional certification

But the employee who has professional experience can deal with all the problems and difficulties facing the field by virtue of his experience

both qualification and experience (PQE, post qualification experienced) 

I say PEERSONALITY,  EXPERIENCE last will be the Certifications/Diploma.

Personality of a person towards job ,has diipline and  also to her/his.colleagues.

Experience is the Most important " ingredient" in our job ,In our life.

Certifiations/Diploma- its just a paper,yes its formality and may as well for  our PRIDE to tell the world " i am a degree holder  etc " 

At the end of the day, everything will depends on our performane at work,,

Apart from experince and certifications, employers must consider the attitude of a potential candidate...Is he willing to learn? Does he handle well under critisim?  Are questions you should consider.

Professional experience + Certifications

Professional experience and professional certificates as well

)both qualification and experience (PQE, post qualification experienced) 

At first when a person called upon is only the basis on his/her CV evaluation and in this process Qualification as well as well presentation only the real substance of calling, then the professional experiance can cater a person to get preference on others.

Professional Experience is, in any way, preffered over Professional Certificates. A good point about professional Certificates is that one can verify their authenticity but they can not ensure whether the employer could benefit from them in the form of real skills that he needs from the intended employee. You can explore a lot more by visiting a place as compared to that what you could get by reading a hundred books about that place.

An employer should not look only at experience or certifications. The most important is to create a profile of the person looked for.

Some of the elements to think about:

- junior / medior / senior profile

- education/certification (specialist or generalist)

- fitting in team (character / cultural background)

- professional background (bringing in new expertise, or reinforcing existing)

- eventually other, more or less related elements, like language knowledge, willing to travel etc.
