Americans pronounce mentorship as MEHN-ter-shihp (/ˈmɛntərˌʃɪp/). In "mentorship", the "t" right after N is dropped — the tongue skips the T stop and moves directly from the N position to the next sound. This is called the Silent T after N, a small move that separates 'classroom' from 'native'. It comes out as MEHN·ter·SHIHP. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "I encourage you to seek out mentorship opportunities within the company".

The textbook way isn't wrong — it's just not how anyone actually says it.
In "mentorship", the "t" right after N is dropped — the tongue skips the T stop and moves directly from the N position to the next sound. /t/ is completely silent — the tongue skips the T stop and moves directly from the N position to the next sound.
Stress falls on the first syllable, not the others. Stretch MEHN — keep everything else short and quick.
Americans use a relaxed retroflex R — the tongue curls back rather than rolling. The R is one continuous sound with the vowel before it, not two separate sounds.
