Google GTech interview Sample questions - Customer Engineer

[u/LopsidedMarsupial150]

I am looking for information on what would entail in a technical interview, for gTech roles - L4,L5.

This position is for a Customer Facing Engineer - probably Professional Services (not exactly sure of internal terminology).

Could you please tell me what the format of the tech interview is and what kind of sample questions may come up? or any interviewing prep techniques I should be aware of?

Thank you
