A formal HR/recruiting prompt. 応募者 ('applicant') is a Sino-Japanese compound. にふさわしい ('suitable to, appropriate for') takes に to mark the criterion — 'appropriate for [applicant].' 職務遂行能力 ('job-performance ability') is a four-character+-compound corporate phrase. The question form があるか is the formal 'does X have Y?' equivalent to possession. Stiff, bureaucratic register typical of HR rubrics.
