Yes, the driver needs to use the turn signal and keep the left turn signal flashing before entering the roundabout, until leaving the roundabout.
No, there is no need to use the turn signal as the car will immediately exit at the first exit and the path is basically straight.
Only a left turn signal is needed after entering the roundabout to prepare for leaving. No turn signal is needed before entering.

In this type of "irregular" "three-way" roundabout, if you are exiting at the first exit, you only need to signal left before entering the roundabout and keep the left turn signal on until you exit the roundabout.
