From what I have heard in that situation you may need to pull up until the stick shaker activates, and then keep around that AoA until you clear the terrain, with the stick shaker activating intermittently, as demonstrated in this simulator session (the relevant part of the video starts at 13:30):

Could MCAS interfere with the terrain escape maneuver? I think that could be the worst moment for MCAS to activate.
Actually, it would be more of a problem if MCAS did not activate. Keep in mind the purpose of MCAS - to augment the control feel at high AOA. If you have a high AOA for any reason - including windshear or GPWS maneuvers - then you are in the flight regime for which MCAS was designed. The original problem occurred when MCAS activated when it wasn’t needed.
