What makes this a question? I don't hear a question intonation in the recording like one would expect in English. Is it the "el" ending of keresel?
The question intonation is there. You can hear a rise in pitch on the next-to-last syllable: Férfiakat ker ES el?. English would end with the pitch rising; Hungarian has an ↗︎↘︎ pitch pattern beginning on the next-to-last syllable. (Except very short one-syllable questions obviously.)
In writing, the only difference between this sentence and the declarative Férfiakat keresel. is the punctuation at the end.
