The telephone interview (arranged via an agency) was regarding a Product Management role.
The technical questions actually asked - by 2 existing Product Managers - were at the level of a graduate engineer, purely memory related rather than technology knowledge related or regarding the needed experience and approach to skills most needed for such a role.
The exact same role was re-posted online in 1-2 days later (by the same agency) with only a title change - as a Technology Architect role, clearly inconsistent and irrelevant.
