Flight was planned ZZZ to SFO with a departure of XA:40. Pick up uneventful. After arriving at airport the flight was delayed to XC:00 due to late inbound aircraft. Ground ops; takeoff; cruise; descent were uneventful. We were being vectored for the Tip Toe 28L. Intercepted final approximately 15 miles out; speed 180 and on glideslope. Approach instructed us to maintain 180 to the bridge. Pilot flying was recently returned furloughed pilot who had flown 6 previous trips after OE. He wanted to slow the aircraft early but ATC wanted 180 to bridge. He asked for the gear down with flaps 1 autopilot and auto thrust engaged. After passing bridge he selected managed speed and the aircraft responded correctly by going full throttle and accelerating to flap 1 speed approximately 210 knots. He wasn't expecting this or really thought about it. He froze for about 5 to 10 seconds so I informed him it was accelerating to flap 1 speed and it had to fix it Manual. Either select a slower speed; use speed brakes and get the flaps done. It did select as lower speed but we were really not getting to a stable condition quickly. At 1200 ft we did get speed back to call for flaps 2 followed quickly by a call for flaps full. Speed was stabilizing so I thought we would be in good shape by 500 ft. Passing 700 feet we heard 'too low flaps'. I selected full flaps and directly a go around. Go around uneventful and follow on approach OK.
The Captain; as pilot monitoring; directed a go-around at 700 feet for GPWS 'too low--flaps' and speed deviations.
